layers: Don't copy all the image subresources every submit

The set of subresources touched by this submission is likely to be very
small compared to the complete set we're tracking. It doesn't make any
sense to copy this entire hashtable in each submit call.

Instead, maintain an overlay table with the submission's modifications
in it.

Saves approx 12s in an internal workload.
