7386342a19 pvr: Add PVR_SELECT() helper macro
For pvr_setup_descriptor_mappings_new() there will be quite a few
variables of which the value depend on the stage so rather than
having all that selection in the `switch` at the beginning of the
function the helper macro provides a compact selection in the
desired scope.

ce67f5ac94 pvr: Write descriptor set addrs table dev addr into shareds
Previously UBOs and various buffers, as well as the native
descriptor sets were DMAed into the shared registers. This added
complexity in allocating the registers and various other places.
We also ended up being in situations were we wouldn't know the size
of a buffer by the time the shaders were being compiled. It would
be possible to determine the size by inspecting the shader but
that would introduce more complexity in the compiler.
To get things working sooner, avoid extra complexity for
now, a different approach was devised.

The driver will write the addresses of the currently bound
descriptor sets into a device buffer. The device buffer is referred
to as the descriptor set addrs table. The dev addr of the table is
written into a shared register. To access the buffers the shader
will first get the address of the descriptor set from the in memory
table. Then get the primary descriptor from the descriptor set. And
finally access the in memory buffer with the address it read from
the descriptor. Essentially there's three level of indirection and
all the buffers are in memory. The shader will know what offset the
primary descriptor is located based on the descriptor set layout.
The descriptor set address could have been written into the shareds
directly but that would require extra handling on the compiler side
so opted to just write the table address instead.

5405277b38 pvr: Put old descriptor set approach behind a hardcoding check
This commit sets up the infrastructure to introduce the new
descriptor set approach while keeping the old paths so the
hard coded apps are still operational. The old paths will be
removed once the compiler can compiler shaders for those apps
and the driver-compiler interface is fully flushed out.

3068f046bc pvr: Check depth/stencil attachment is tile-aligned
The hardware requires depth/stencil attachments to be size-aligned to
the zls tile size (as defined by rogue_get_zls_tile_size_xy()).

In practice however, this is a tiny edge case. The restriction only
applies during some operations, and any attachment larger than the tile
size will be twiddled and over-allocated into alignment beforehand.

This commit also adds the mentioned rogue_get_zls_tile_size_xy()
function. These values differ from the regular tile_size_{x,y} feature
values in some cases. Instead of including them as features as well, we
compute them directly.

6a9364f4bc pvr: Change pvr_get_hw_clear_color() to pack based on accum formats.
`pvr_get_hw_clear_color()` now packs formats based on the accum
format which is how the hw deals with the formats internally and
might not line up exactly with the vk format representation.

E.g. R5G6B5_UNORM_PACK16 uses the U8 accum format so the USC will
internally use 3 bytes (1 per component) to deal with it instead
of 2 bytes which the vk format specifies. On USC EMITPIX, the PBE
will pack the results to 2 bytes using PACKMODE_R5G6B5 resulting
in the final value being in the vk format representation.

6a35563de0 pvr: Fix possible seg fault on csb copy.
When copying the secondary command buffer's deferred control stream
to the main stream we have to first allocate space in the main
stream. In case the allocation failed we were attempting to
memcpy() to a NULL destination causing a NULL dereference.

This fixes CID 1515977.

b03e73a024 pvr: Fix allocation size passed in pvr_cmd_buffer_alloc_mem.
pvr_cmd_buffer_alloc_mem takes size in bytes. This change
fixes the invocations which assume it to be size in dwords.
