nvk: Rework descriptor writes

In particular, this makes us only touch the descriptor UBO memory as a
memcpy destination unless we're doing a descriptor copy.  This should be
much better for mapped GPU memory than the read-modify-write required by
our previous implementation of image descriptor writes with their 12:20
configuration.
