drm/i915/vm_bind: Support private and shared BOs
Add uapi allowing user to specify a BO as private to a specified VM
during the BO creation.
VM private BOs can only be mapped on the specified VM and can't be
dma_buf exported. VM private BOs share a single common dma_resv object,
hence has a performance advantage requiring a single dma_resv object
update in the execbuf path compared to non-private (shared) BOs.
