This is an OS behavior to have failed an allocation with a
const buffer backing storage (PAGE_READONLY attribute set)
ReadOnly flag allows to create allocation with read-only
backing storage

- 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.

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.

previous handle has been freed.
- Release the Ipc Memory Handle when zeMemPutIpcHandle is called.
- Create a new IPC Handle for tracking thru zeMemGetAllocProperties
when ze_external_memory_export_fd_t is used.
- Convert FD to opaque IPC handle and IPC Handle to FD.
