Subject: Remove GrResourceIOProcessor.

Fold its functionality into GrPrimitiveProcessor and GrFragmentProcessor.

Make each have its own TextureSampler nested class. Currently the only
difference is that fragment processors lose the ability to inject their
samplers into the vertex shader. However, this facilitates refactoring
GrPrimitiveProcessor's TextureSampler class such that the textures are
specified separately from the TextureSampler.
