performance: program pat index on mtl linux

Browse Source 
Enable programming pat indexes on mtl linux for device buffers.

Change DrmMemoryManager::allocateMemoryByKMD to use gemCreateExt.

Set mmap flags based on coherency.
Map as write back on legacy and coherent.
On non-coherent map as write combined.

Changes currently disabled, to enable use debug keys:
DisableGemCreateExtSetPat=0
UseGemCreateExtInAllocateMemoryByKMD=1

Reorder BufferObject to decrease padding.
