David Stevens 534f873f1a devices: vvu: support shared memory regions 
Add support for SHMEM_MAP and SHMEM_UNMAP. This requires mapping the
buffer in the device backend via VFIO and reconstituting it as a udmabuf
in the proxy device. It's also necessary to handle unmap operations in
the device backend, to unmap the buffer.

BUG=b:201745804
TEST=launch sibling VM on manatee
