Add runtime color filter and shader modes to the SkSL compiler These enforce stricter rules about the signature of main, and each one uses a separate pre-include module. That prevents color filters from being able to reference sk_FragCoord (or coords passed to main) at all. It also limits the versions of sample() that are exposed. In the new world, an effect created for a specific stage of the Skia pipeline can only be used to create instances of that stage (SkShader or SkColorFilter). For now, SkRuntimeEffect::Make uses kRuntimeEffect, which continues to be more lenient and allow creation of either shaders or color filters from a single effect. After we migrate all clients, we can deprecate and then delete that mode.
