- 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
