When vaapi generated dmabuf surfaces are shared across processes we need to know if it's safe to recycle them so we need to hold global reference count for them.

This patch implements:
- Global surface UID for better tracking/debugging. The UID is passes acros all processes so we can track
surface usage. - WaylandAllocateShmMemory() function which uses shm_open() instead of files at tmp for Shm memory creation.
- DMABufRefcount() class based on POSIX semaphores created on top of shm memory.
