Delete GPU alpha clip masks
The cost of switching render targets on each draw to make a custom
clip is enormous. There are virtually no circumstances where this will
outperform our cached, multi-threaded software mask generator. The
tried-and-true approach to clipping on-GPU is with analytic FPs. And
now that we support CCPR clip FPs, there ulitmately should be very few
clip stacks that even require a mask as long as they don't use
deprecated SkClipOps.
