In this mode, which can be activated with V3D_DEBUG=always_flush like
in the GL driver, we flush every draw call separately. For now this
is useful for debugging, but we can also set the flag internally on
specific jobs when we identify scenarios where we need the same behavior.

It is valid to submit with an empty list ofcommand buffers, however,
we still need to wait on the pWaitSemaphores provided and only signal
the pSignalSemaphores and fence once we have finished waiting on them
to honor the semantics of the submission.
Because waiting and signaling happens in the kernel, the easiest way
to do this is to submit a trivial no-op job to the GPU. To do this,
we need to refactor some of our code so that code that might have been
operating on a command buffer starts operating on a job instead, so we
can resuse most of our infrastructure to create the no-op job.
Additionally, because no-op jobs are created internally by the driver,
we are responsible for destroying them too. For this, we bind a fence
to each no-op job we submit and we test for completion of in-flight
no-op jobs (and destory them if completed) every time vkQueueSubmit
is called.

There are a handful of tests that simulate 'out of memory' situations
during swapchain image creation, and these can lead to failed job
allocations when the driver is running on the prime blit path, as that
involves creating a command buffer. The tests expect us to handle this
scenario gracefully and return an appropriate OOM error as a result.
This make sure we don't try to dereference a job if we failed to allocate
it so we don't crash and can return the OOM error gracefully in the
process.

This was intended to check that we only got
VK_COMMAND_BUFFER_USAGE_RENDER_PASS_CONTINUE_BIT
on secondary command buffers, but the spec states that this flag
should be ignored for primary command buffers.

We were clearing memory to 0 on create and reset, including the
loader data, which is not correct on reset since it would cleat
the loader dispatch table for the command buffer. We should only
clear driver data.
Also, don't use vk_zalloc for the command buffer allocation, since
we are already clearing on reset and we always reset when we begin
recording.

This puts all the information required to setup frame tiling into
v3dv_frame_tiling so we no longer need a framebuffer to start a
frame. This makes the code simpler, since frame tiling calculations
happen automatically when we start a new frame and simplifies
the implementation of copy and clear operations that used to
requiere that we setup a fake framebuffer with no actual attachments,
which was a bit of a kludge.
Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/6766>
So far we have been getting away with computing frame tiling information for
the framebuffer object, but that is not correct, since different subpasses
may access different subsets of the framebuffer, with each requiring a
different configuration because the number of render targets and the maximum
bpp can change for each subpass.
This adds a v3dv_frame_tiling struct to keep the frame tiling information and
rewrites the code to compute this for every new job we start.

When we create a new job for a new subpass, we might have to finish
the current job for the previous subpass, so it is important that we
we don't get ahead of ourselves and increment the current subpass index
in the command buffer state until we are really done finishing the
previous job.

We were storing the format of the base miplevel in the image view and
we were typically using that instead of the taking the format from
the appropriate image slice. This was a problem when loading or storing
a miplevel other than the base which happened to have a different format.
This also removed the tiling field from the image view to avoid repeating
the same mistake in the future.

By default they are trivially lowered to load_uniform.
We still need to allocate an UBO for push constants, used for those
that are accessed using a non-const index. This is automatically
handled by the compiler, as it cames back as asking a
QUNIFORM_UBO_ADDR. This is what already does for gallium.
Note that if needing the UBO, we are uploading the full push constant
data. An improvement would be to try to upload only the data that
needs to rely on the UBO (so non-const accesses to uniforms).
Also, the code is not handling getting out of space from the UBO
bo. This would be tackled at a different commit.

From the Vulkan spec:
"When an image view of a depth/stencil image is used as a
depth/stencil framebuffer attachment, the aspectMask is ignored
and both depth and stencil image subresources are used."
So in that scenario, we ignore the aspect mask on the view and go
check the actual format of the underlying image to decide if we
have depth or depth+stencil aspects.
This gets VkRunner's depth-buffer.shader_test to pass.
Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/6766>
For now this only implements a fast path using the tile buffer, so it
can only be used when clearing full images, but this is good enough
for VkRunner.
The implementation is a bit tricky because this command executes
inside a render pass, and yet, since we are using the tile buffer to
clear, this needs to go in its own job. This means that with this, we
need to be able to split a subpass into multiple jobs which creates
some issues.
For example, certain operations, such as the subpass load operation
(particularly if it is a clear) should only happen on the first job of
the subpass and subsequent jobs in the same subpass should always
load.
Similarly, we should not discard the last store on an attachment
unless we know it is the last job for the last subpass that uses the
attachment.
To handle these cases we add two new flags to the job, one to know if
the job is not the first in a subpass (is_subpass_continue) and
another one to know if a job is the last in a subpass
(is_subpass_finish).

For that we include the array_index when asking for a ubo/ssbo index
from the descriptor_map.
Until now, array_index was not included, but the descriptor_map took
into account the array_size. This had the advantage that you only need
a entry on the descriptor map, and the index was properly return.
But this make it complex to get back the set, binding and array_index
back from the ubo/ssbo binding. So it was more easy to just add
array_index. Somehow now the "key" on the descriptor map is the
combination of (set, binding, array_index).
Note that this also make sense as the vulkan api identifies each array
index as a descriptor, so for example, from spec,
VkDescriptorSetLayoutBinding:descriptorCount
"descriptorCount is the number of descriptors contained in the
binding, accessed in a shader as an array"

Focused on getting the basic UBO and SSBO cases implemented. So no
dynamic offset, push contanst, samplers, and so on.
This include a initial implementation for CreatedescriptorPool,
CreateDescriptorSetLayout, AllocateDescriptorSets,
UpdateDescriptorSets, CreatePipelineLayout, and CmdBindDescriptorSets.
Also introduces lowering vulkan intrinsics. For now just
vulkan_resource_index.
We also introduce a descriptor_map, in this case for the ubos and
ssbos, used to assign a index for each set/binding combination, that
would be used when filling back the details of the ubo or ssbo on
other places (like QUNIFORM_UBO_ADDR or QUNIFORM_SSBO_OFFSET).
Note that at this point we don't need a bo for the descriptor pool, so
descriptor sets are not getting a piece of it. That would likely
change as we start to support more descriptor set types.

The general idea is that we always emit from our dynamic state, and when
a particular piece of state is not dynamic, we just set our dynamic state
from the pipeline state, however, the implementation was quite confusing:
the mask of dynamic states flagged states that were not dynamic and some
places woud mix dirty flags and dynamic state flags. We also were not
updating the dynamic state mask in the command buffer, etc.
This patch, hopefully, simplifies all this and makes it less confusing,
starting by making the dynamic state mask flag dynamic states, fixing
the places where we would confuse dirty state flags with dynamic state
flags, making sure that our command buffer state is setup correctly
and that we only emit state when it is actually dirty.

We were not computing viewport transform for static viewports provided with
the pipeline state. Also, we were not copying the transform into the command

This is only used when doing a clif/cle dump, but makes it far easier
to understand.
Most names are the same that the ones used at v3d (CL, tile_alloc,
TDSA), except those that on v3d were labelled as "resource", as right
now we don't have a resource uploader that englobes different
things. In fact, the good thing of not having that uploader is that
individual bos has a more accurate description of their purpose.

Otherwise we would lose updates relevant to subsequent subpasses in
the same renderpass that read or partially write the attachment.
The only scenario where we can safely do this is on the last subpass
that uses the attachment, so long as we don't need to emit the store
for the clear.
This also fixes a bug in the computation of the first subpass that
uses an attachment.

This ignores stencil for now and focuses on depth testing without
support for early depth testing.
To implement this we need to start considering how many of our
framebuffer attachments are color attachments, since some of the
computations we use to determine tile sizes and binning configuration
depend on this.

We can't prepack all the record, as addresses need the job, and
uniforms depend on dynamic value.
Also due cl_emit_with_prepacked and v3dv_pack asserting correct
values, we need to define two values twice, that lead to move
vpm_config to the pipeline. In any case, the latter will be useful
when we start to prepack more stuff.
