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.

For all execution paths where needed, use `BufferObjectHandleWrapper`
instances for registration of BO-handles and try to obtain shared
ownership. This allows both sides of IPC communication to be implemented
in the same process and avoid the double-free problem on a BufferObject
of the same handle.
Currently there are two pairs of such calls:
* `zeEventPoolGetIpcHandle()` + `zeEventPoolOpenIpcHandle()`
* `zeMemGetIpcHandle()` + `zeMemOpenIpcHandle()`
The capability of executing both sides from the same process is useful
for testing but not only.

Changed NumaLibrary to read default policy instead of using
the address-based policy, and remove unnecessary argument.
Removed numaif.h from the repo as it is no longer required.

Modified ioctl_helper_prelim to support the extension of gem_create_ext,
i.e. prelim_drm_i915_gem_create_ext_mempolicy.
Added two debug variables to be used for the mempolicy extension.
Modified functions in memory_info and drm_memory_manager to support extension
Added numaif.h from https://github.com/numactl/numactl/tree/master,
v2.0.14

Unify `getIpcMemHandle()` and `getIpcMemHandles()` and fix the issue of
missing IPC handles registration while reducing copy-pasted code.
Also replace `boHandle` with `boHandleWrapper` to leverage `refCount`
properly and avoid double-free.

- Change the heap/pageSize used based on the size of the reservation
required and the device heaps available.
- Return the page size required based on the size requested by the user
for virtual reservation and the devices on the system.
- Check the size passed in by the user in memory map and physical memory
allocation is valid for the heap and page size that is required.
