Reduce max # of AA Quads that can be merged or chained into a single GrTextureOp (take 2)

It is, arguably, not a good metric but the max number of AA Quads that are merged or chained together across all Skia's GMs and SKPs is 276.

This should also reduce the memory consumed from 245,760 bytes to 30,720 bytes.
