We were accidentally leaving XY_BLOCK_COPY_BLT's Source and Destination
MOCS fields set to 0 (Error: Reserved for Non-Use) on Gfx12.0 systems.
This was causing assert fails in debug builds, since we try to ensure
that we don't do that. In theory, MOCS 0 is supposed to be equivalent
to MOCS 2 (all the caching), but...we probably ought to use MOCS 3
(uncached). Every Gfx12.5+ platform requires it, so although there
isn't a note about Gfx12.0 needing that, it's possible that it does.
We're currently only using the blitter for DRI PRIME blits on Gfx12.0,
anyway, and I think we're flushing all the caches regardless.
This bug was somewhat obscure to hit:
- You need a hybrid graphics system with Gfx12.0 and some other GPU
- You have to be using "reverse PRIME", i.e. rendering on the integrated
GPU and displaying on the discrete one. This is not the common case.
- You have to be using a debug build.
No observable performance delta in GfxBench5 Car Chase (an arbitrary
program) when rendering on Alderlake GT1 and displaying on an Arc A770.

See HSD 22015614752. We have issues when multiple engines access the
same CCS cacheline in parallel. This can happen in a Vulkan application
that uses different queues to operate on different subresources.
To resolve this, this patch prefers Tile64 when an image has multiple
subresources and disallows CCS if such an image lacks that tiling.

There are multiple problems currently :
- blorp blitter commands overwrite the protection value coming from
the driver
- anv & iris are using render target MOCS for compute commands
Driver already have the ability to pass the MOCS values so we choose
to stick to that in this change. But now the driver need to select the
right MOCS depending on the engine the commands are going to run onto.

The previous patch changed the gfx12 CCS initial aux state from
pass-through to compressed-no-clear. This isn't always accurate.
This patch determines if a CCS is in the pass-through state by
inspecting the associated resources' bo field. In order to do that
clearly, move aux-state initialization out of
iris_resource_configure_aux (which can be called before BO creation).
Split up that logic and move the pieces into iris_resource_from_handle,
iris_resource_init_aux_buf, and a new function in ISL.
