Instead of using the clear color conversion feature by the hardware, use
software to write out the converted clear color pixel.
When testing a patch which moves a state cache invalidate to occur after
fast clears instead of before, this prevents the following failures on

The hardware's clear color conversion feature unfortunately requires
invalidating the texture cache for every fast clear. To avoid the
performance penalty that comes with the invalidation, avoid using the
hardware feature and write out the converted clear color pixel
ourselves.

This improves drivers in the following ways:
* iris_hiz_exec() and crocus_hiz_exec() gets rid of the narrowly-used
update_clear_depth parameters.
* iris avoids fast-clearing if the aux state is CLEAR. crocus avoids
this too, but didn't actually need it in the first place.
* iris updates the value once per fast_clear_depth() call instead of
doing an update for each layer being cleared.
* anv now updates the clear value when transitioning from an undefined
layout instead of doing so on every fast-clear. This should be safer
because we don't perform state cache invalidates when changing the
clear value. So, existing surface states won't have any stale values.

The new workaround tries to strike a balance between simplicity and
functionality (for testing purposes). Instead of checking for the
alignment of a specific LOD when fast-clearing, we take an
all-or-nothing approach for LOD1+.
I haven't found any app to clear LOD1+ except for a Dirt Rally trace
some time ago. If I remember correctly, that trace clears all LODs,
doesn't render to them, then clears again with a different color,
incurring resolves. So, skipping LOD1+ fast clears will avoid those
resolves. Other apps I tested include Synmark2, glmark2, GfxBench5, and
the Vulkan games in internal our benchmarking tool.
Now that we've added updated and simplified checks in the drivers
themselves, we delete blorp_can_hiz_clear_depth.

None of our tracked games use partial depth clears, so only allow it in
simple cases for testing purposes. This change also fixes an issue on
gfx8, where we had been accidentally disabling full surface clears if
the LOD was not 8x4 aligned.

I did some more debugging of this feature, but this time with a modified
version of the piglit test, ./bin/depthstencil-render-miplevels.
I modified the test to:
* Control which LOD to stop populating/clearing
* Print out the results of readpixels to stderr
From there, I could see how different surface dimensions affected
fast-clears. Depending on the surface dimensions, fast-clearing an LOD
above the LOD0 could cause other LODs to be cleared and/or cause the
targeted LOD to be only partially cleared (for example, when the LOD0
dimension is 66x66 and the test doesn't clear LOD3+). This never happens
when fast-clearing LOD0 however.

For correct fast-clearing with HiZ+CCS, we require roughly 16x8
alignment of LODs. The next patch will cause drivers to ignore the
alignment of LOD0, so align the qpitch to 8 to avoid breakage and so
that fast clears will be enabled more often.
Prevents failures with the piglit test case:
./bin/fbo-depth-array depth-clear -fbo

Xe2 has 2 requirements for preferred SLM size:
- this value needs to be >= then SLM size
- this value must be less than shared SLM/L1$ RAM in the sub-slice of platform
Also Xe2 don't have the special '0' encode that sets preferred SLM
allocation size to the maximum supported.
So here setting a value that is equal or larger than SLM size.
It was always setting SLM_ENCODES_128K for LNL A0 stepping probably
because of Wa_16018610683 but this restriction applies to all Xe2
platforms, also because of the first restriction mentioned here
this workaround is not being properly implemented, will fix that
in the next patch.
We should have a formula to calculate a preferred SLM allocation size
for gfx125 and Xe2 platfoms but until that this is enough to fix at
least the applications and tests below on LNL:
- GFXBench Aztec Ruins VK
- GravityMark VK
- Wildlife Extreme VK
- 5 crucible tests
