The DRM shmem helper includes common code useful for drivers which
allocate GEM objects as anonymous shmem. Add a Rust abstraction for
this. Drivers can choose the raw GEM implementation or the shmem layer,
depending on their needs.

Lyude changelog:
* Rebase
* Squash "rust: drm: device: Convert Device to AlwaysRefCounted" as this
  commit doesn't compile without it anyway
