sna: Use direct uploads into a Damage tracked for v.small operations
If the batch is being frequently flushed due to Damage+Composite
tracking, we cannot amalgamate the small copies into the destination and
so end up sending thousands and thousands of tiny batches with tiny
render copies hogging the GPU.
