drm/vmwgfx: Add support for UA view commands
Virtual device now support new commands to manage unordered access
views. Allow them as part of user-space command buffer. This involves
adding UA view cotable, binding tracker info, new view type and command
verifier functions.
v2: fix comment typo
v3: style fixes (don't use deprecated PTR_RET)
