Add mechanism to preallocate cmd buffer allocations in command stream
receiver reusable allocations list per command queue initialized.
This should limit additional allocations during hot loop.
Needs to be enabled in subsequent commits by setting product helper
method.

Temporarily opt-out from additional compatibility checks
on DG2 for Blender AOT-compiled kernels.
This prevents a long kernel recompilation.
Additionally, same behavior can be enforced for other applications
manually via NEO debug key named DoNotUseProductConfigForValidationWa.

Added getDefaultDeviceHierarchy call that describes default device
hierarchy for a gfx core. Refactored L0 and OCL paths to use this
value by default and override this value when user sets
ZE_FLAT_DEVICE_HIERARCHY environment variable or
ReturnSubDevicesAsApiDevices debug key.
Updated ReturnSubDevicesAsApiDevices to force COMPOSITE device hierarchy
when set to 0.

Program barrier to task stream, before next enqueue kernel.
This will reduce the number of batch buffer starts for sequences of

Add debug flag ProgramBarrierInCommandStreamTask to program barrier
pipe control in task command stream instead of csr command stream.
This will reduce the number of batch buffer starts.

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.

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.

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.
