drm/vkms: Add dumb operations
VKMS currently does not handle dumb data, and as a consequence, it does
not provide mechanisms for handling gem. This commit adds the necessary
support for gem object/handler and the dumb functions.
Changes since V1:
Daniel Vetter:
- Add dumb buffer support to the same patchset
Changes since V2:
Haneen:
- Add missing gem_free_object_unlocked callback to fix the warning
"Memory manager not clean during takedown"
