Brian Osman 9194675a3e SkSL: In the front-end, rename PipelineStage to RuntimeEffect
This maps to usage better, and makes some code simpler to understand.
Note that there is still a PipelineStage *back-end*, which is specific
to the runtime-effect FP. A kRuntimeEffect_Kind program can be used to
generate a PipelineStage (for the GPU backend), or an skvm program (for
the CPU backend).
