In iris, use the CCS scale down factor to calculate the impact of CCS on
TBIMR tile sizes. Even though we fall back to a seemingly less accurate
method to calculate the impact of CCS, it ends up giving the same
answer, 1bpp. Anv already uses this factor, so this patch replaces the
constant with this macro.
There are two benefits to doing this:
1) Consistency between anv and iris.
2) Preparation for a future where we no longer use ISL surfaces to
describe CCS on Xe+. In fact, in iris, we already don't create such
surfaces on ACM.
I considered using INTEL_AUX_MAP_MAIN_SIZE_SCALEDOWN for the calculation
in both drivers, but the naming is aux-map specific and the scaledown
actually exists on flat-ccs platforms as well.
So, we introduce a new macro for all Xe platforms, currently only used
for the specific use case of TBIMR calculations. We can add more such
macros for future platforms, as needed.

Introduce a macro defining the alignment which aux data start addresses
should have. This alignment is for the worst case of the CCS buffer
being included in a dmabuf. Although a smaller alignment is possible for
non-dmabuf cases on TGL, no drivers would make use of that today as they
place CCS surfaces directly after tiled surfaces.

Up to now preferred SLM size was being set to maximum preferred SLM
size for GFX 12.5 platforms and to workgroup SLM size for Xe2 but
neither of those values are the optimal.
The optimal value is:
<number of workgroups that can run per subslice> * <workgroup SLM size>

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

The debug identifier is put into the captured buffers for error
capture. This helps us figure out what version of the driver people
are running when encountering a GPU hang. This identifier has the
git-sha1 + driver name.
libintel_dev is also a dependency of the compiler so any change to the
git-sha1 also triggers recompile which we want to avoid.
This changes moves the debug identifier to src/intel/common which
drivers already depend on, so the compiler is not affected anymore.

The round up in 'next_address_8kb = DIV_ROUND_UP(push_constant_kb, 8)'
was not decreasing the amount of URB available for Mesh and Task, what
could cause an over allocation of URB.
There was also no minimum entries enforcement for Mesh and Task, what
could cause 0 r.mesh_entries to be set in a case where tue_size_dw is
90% > than mue_size_dw. Same for r.task_entries when Task is enabled.
Also adding a few more asserts to help debug.
This fixes at least dEQP-VK.mesh_shader.ext.properties.mesh_payload_size
in LNL but it has potential to fixes other Mesh tests as well.
