Insert a flush after a depth decompression pass if the texture
was fast cleared.
This fixes a corruption which seems to only affect gfx10.3 chips.
Ideally we should also clear tex->need_flush_after_depth_decompression
after a flush but there's no easy way for this so this commit will
introduce extra flushes.

This generally works well.
There are new cases that select Wave32, and there are shader profiles
which adjust that.

When a resource is multisampled, we usually submit a multisampling
resolving blit before we present it or use it in some other way, but
currently we don't always flush the cmd buffer before flushing the
frontbuffer, this commit fixes that.

We can't map the CCS on this platform to initialize it into the
PASS_THROUGH state. This can cause issues with optimizations in the
driver that rely on this state.
For example, after rendering to a surface with AUX_NONE, we can then
render to it with AUX_CCS_E without an ambiguate in between (if the CCS
in the PASS_THROUGH state). If that state was incorrect and the aux was
actually compressed, there can be rendering corruption because the
contents may be misinterpreted on the second render.
Use a more accurate initial aux state to avoid these issues.
One notable change in behavior here is that aux surfaces can be created
with fast-cleared blocks even though the caller may specify a modifier
that doesn't support fast clears. This should be fine, so long as all HW
units that can access these surfaces can handle that bit-pattern. We
haven't seen an applicable restriction yet.

The assert was introduced in a function that allocated an auxiliary
surface BO, iris_resource_alloc_aux. After refactors, the function it's
in now, iris_resource_configure_aux, no longer does this allocation.
Drop the assert because its purpose is unclear and it's no longer
relevant for CCS on XeHP.

The only depth/stencil aux usage that can actually use the BO is
ISL_AUX_USAGE_HIZ_CCS_WT. Even with that aux usage, iris may disable
sampling depending on the surface configuration.
Allocate the clear color BO when it'd be usable, not just when the
auxiliary surface size is non-zero on ICL+. This prepares for CCS on
XeHP, which won't have an auxiliary surface.

While setting up DITHER_MODE allows alpha blending to work properly
together with dithering on new GPUs (those with PE_DITHER_FIX), older
cores still change the render target. As dithering is optional and
implementation defined we can simply disable it on the affected GPUs,
when alpha blending is enabled to work around this bug.

This moves some ops down to when they're needed, generally reducing the
number of temps in use. It's not always a win -- sometimes you can end up
moving a generator of a component used by a nir_op_vec down, which means
that op's sources stay live while the vec (whose register likely gets
coalesced with the ops creating it) is also live. But it's generally
good.

1. We can create resource with size of "1" on drm, because size
is not passed to the renderer.
2. We can't create resource with size of "1" on vtest, because shmem
is created based on that.
3. If renderer supports copy_transfer_from_host, then use staging
buffer for transfer in both ways to and from host.
This will allow to reduce memory consumption in the guest.
v2:
- add inline function for checking if we can use this optimization
- add check in readback path. If renderer doesn't support
copy transfer from host, then we need to go with previous
path in readback (through transfer_get ioctl)
v3:
- fix logic for readback
v4:
- refactor the implementation to integrate it more to
existing code base
v5:
- reuse COPY_TRANSFER3D in both directions
