drm/vkms: Add framebuffer and plane helpers 



This patch appends the minimum helpers related to framebuffer and plane
to make vkms minimally usable.

Changes since V1:
- None
Changes since V2:
- Squash "Add plane helper struct" and "Add helper for framebuffer
  create"
Changes since V3:
 Daniel Vetter:
 - Remove atomic_check from plane helper
