When upstream ioctl helper is created it will try to create small
allocation, adding I915_GEM_CREATE_EXT_SET_PAT extension. If it
succeeds, for all resources with valid pat index value it will then
explicitly program pat index value with gem create ext call.
PrintBOCreateDestroyResult value can be used to:
- print whether the set pat extension is supported by the kernel, when
ioctl helper is created
- print whether set pat extension was added for a given gem create ext
call and what pat index value was programmed
Note: introduced changes are disabled by defualt.
Toggle DisableGemCreateExtSetPat can be used to enable new functionality.

Temporarily reverting back to previously reported value to avoid corner-case
regression. Intent is reintroduce as soon as regressions are rootcaused.
This only affects Linux.

By default prefer allocating memory first by KMD, instead of malloc first.
By default prefer not caching allocations on MTL devices. This results
in allocations being handled with non-coherent pat index.
For integrated devices when caching is not preferred do not allow
direct memory access in CPU domain. For map/unmap operations create
a dedicated memory allocation for CPU access, instead of accessing it
directly, reusing the same logic as when mapping/unmapping local memory.

The new classes SysmanKmdInterface, SysmanKmdInterfaceI915 and
SysmanKmdInterfaceXe have been introduced.
A map is maintained in the SysmanKmdInterfaceI915 and
SysmanKmdInterfaceXe class for the sysfs file names.
The access specifier of the function getDrmVersion has been changed from
protected to public so as to use it in the sysman code. This is required
for the SysmanKmdInterface pointer to point to the
SysmanKmdInterfaceI915 and SysmanKmdInterfaceXe accordingly.
The ULTs have been added for the new sysfs file path corresponding to
the i915 and the Xe driver.

- Preserve releases on CMake level.
- Instead of generating builtins per platform, generate them per-release
(+ correct naming accordingly).
- Stop using revisions in builtin compilation logic path, as they are
already embedded in release (device ip).
- Remove platform names & revisions from names for generated files
(related to builtins).
- Remove unnecessary code, refactor ULT logic.

The previous name "pageSize2Mb" defined in
shared/source/helpers/constant.h is inconsistent to other variable,
i.e. pageSize64k.
Furthermore, it's a bit misleading because the page size is defined in
Megabytes (MB), not in Megabits (Mb).

New debug keys added:
EnableBOChunking is now a mask
0 = no chunking (default).
1 = shared allocations only
2 = device allocations only
3 = shared and device allocations
MinimalAllocationSizeForChunking sets the minimum allocation
size to apply chunking. Default is 2MB.

With direct submission disabled this resulted in waitTimeout long enough
that kmdWait fallback was rarely used.
This caused more CPU spin time.
