Source 2 games segfault if certain buffers are not able to use the same
memory types as images. CS2 specifically expects this to be the case for
vertex and index buffers (VK_BUFFER_USAGE_2_INDEX_BUFFER_BIT,
VK_BUFFER_USAGE_2_VERTEX_BUFFER_BIT). I have not tested other Source 2
games to see how much the requirement differs for the usage (if at all).
Up until now, we've disabled CCS for the Source 2 engine with the
anv_disable_xe2_ccs driconf option. However, this option is not great
for performance. So, replace this with a new option to allow the same
memory types we use for images on buffers - anv_enable_buffer_comp.
Compression of buffers is generally not good for performance. I
collected the result of unconditionally enabling the feature in the
performance CI on BMG. I used the default configuration to average the
result of two runs of each trace.
The CI reports that 4 game traces would regress between 0.44-1.01% FPS
with buffer compression. However, the CI actually shows it to be
beneficial in three of our game traces:
* Cyberpunk-trace-dx12-1080p-high 106.51%
* Hitman3-trace-dx12-1080p-med 101.59%
* Blackops3-trace-dx11-1080p-high 100.44%
So, enable the option for the two games we already have driconf entries
for, Cyberpunk and Hitman3.
Of course, also enable the option for Source 2 games. Casey Bowman
reports that on BMG, some frame times drop from ~15ms to ~7ms in CS2.
This is in large part due to the removal of HiZ resolves, which is a
consequence of the game now using of HIZ_CCS_WT instead of plain HIZ.

This title incorrectly tries to allocate descriptor sets larger than
the number of sampler items in the descriptor pool.
Workaround by taking other largest item count in the descriptor pool
and use that for samplers.

This avoids massively long shader compile times when there is lots of
spilling, at a minor cost of a few more spills/fills. Choose 15 as it is
already the default used by the Cyberpunk 2077 driconf workaround.
Surprisingly the number of additional spills/fills are miniscule in
fossil-db:
Instructions in all programs: 152680595 -> 152681525 (+0.0%)
SENDs in all programs: 7672789 -> 7672789 (+0.0%)
Loops in all programs: 48469 -> 48469 (+0.0%)
Cycles in all programs: 11981743456 -> 11984228708 (+0.0%)
Spills in all programs: 42989 -> 42779 (-0.5%)
Fills in all programs: 76380 -> 76776 (+0.5%)
partly because of the chaotic unpredictability that the choice of
registe to spill has on a shader. For example, this patch massively
helps some shaders in terms of spills/fills:
Spills helped fossils/fossil-db/steam-native/red_dead_redemption2.vk-g6.foz/4101ff9c9b83bf22/SIMD8 fragment: 3208 -> 2894 (-9.8%)

When barriers are used in invalid shaders with non-uniform control flow
we might get a hang. Forcing 32-wide group can help by making it more
probable that barrier instruction is executed by at least one channel
in each thread, and thus hang will be avoided. This shouldn't affect
Xe2+, where active-thread-only barriers are used anyway.

Dota 2 and Counter-Strike 2 really want to be able to allocate memory
for both VkImages and VkBuffers from the same memory type. Xe2's
special compression-only memory type does not support buffers, which
makes these games crash. Disable CCS on these games as a workaround.
This is a temporary workaround as we're still working towards a
long-term solution (either by fixing the engine or finding a way
better expose our memory types).
