The main idea here is to simplify, mainly to reduce the number of SkRasterPipeline objects the blitter holds.
- Use SkBlendMode instead of SkXfermode, just store SkBlendMode.
- Fuse the shader and color filter together into one SkRasterPipeline
during blitter creation.
- I noticed all calls to append_load_d() and append_store() now have the same ctx argument, so I folded that through.
I'll be following up with more of this sort of refactoring... I think I can fold everything into a single SkRasterPipeline during blitter creation now, but I'll want to make sure I've got my ducks in a row for how that works with pipeline strength reduction (like skipping dst loads when drawing in Src mode).
