4ace478545 util/rust: Add handle type detection to descriptor API 
This enhances the DescriptorType enum to include the
memory handle type (DMABUF vs SHM) alongside the size,
allowing consumers to differentiate between DMA-BUF and
shared memory file descriptors without redundant code.

e0b1193361 mesa: import mesa3d_util 
This is intended to a Rust analog to "src/util", which has
many utilities used by Mesa developers.  This is mostly
a copy of ${crosvm} rutabaga_gfx/src/rutabaga_os (which will
be deleted in favor of this crate).

Key constructs include:
    - SharedMemory
    - MemoryMapping
    - Tube (sockets, essentially)
    - OwnedDescriptor (HANDLE or fd-based)
    - WaitContext (epoll, ..)

As one would expect, Linux implementations are the most complete.
