- Added support for creating and managing opaque IPC NT handles in the
WDDM layer.
- Introduced a new flag `shareableWithoutNTHandle` to indicate if memory
can be shared without an NT handle.
- Updated the `isShareableMemory` method to accommodate this new flag.
- Added debug variable EnableShareableWithoutNTHandle to control the
behavior of sharing memory without NT handles until requested.
- Updated Linux path to enable sharing DMA Buf FDs between processes
for use in pidfd_getfd
- Updated getfd and get IPC Handle helper functions to support opaque or
previous versions

- Added support for L0 to query Vector Width Properties which allows for
querying all the supported vector widths and their prefferred and
native vector widths per data type.
- Updated shared code to support querying the same values thru
getPreferredVectorWidth* and getNativeVectorWidth* helper functions
for OpenCL and Level Zero.
- Initial support for reporting base values for the vector
widths with future support for reporting different values per platform and
based on the SIMD/SIMT size used.
