plumb y through to SkJumper

There'll still be a little more refactoring after this, but this is the
main thing we want to do.

This makes y available in a general-purpose register in pipeline stages,
just like x.  Stages that need y (seed_shader and dither) can just use
it rather than pulling it off a context pointer.  seed_shader loses its
context pointer, and dither's gets simpler.
