drm/amdgpu: add VM generation token
Instead of using the VRAM lost counter add a 64bit token which indicates
if a context or job is still valid to use.
Should the VRAM be lost or the page tables need re-creation the token will
change indicating that userspace needs to act and re-create the contexts
and re-submit the work.
