This is a reland of GrDomainEffect with significant changes:

1) It correctly handles GPs that have a local matrix

2) It applies its rectangle after the child FP's coord transform. It makes
the child's transform be a no-op and the builder will no longer insert code
or uniforms for the child transform. The domain effect adds its own coord
transform with the same settings as the child's original transform. The result
is that the generated code only has one coord transform matrix and that matrix
is applies in the vertex shader. The previous version of this effect applied
the transform in the fragment shader.
