Add a GrGpuGL reference for GrGLProgram/GrGLUniformManager

Add a GrGpuGL reference for GrGLProgram/GrGLUniformManager

Updates GrGLProgram and GrGLUniformManager to keep a GrGpuGL reference
instead of one for GrGLContextInfo. No change in functionality, this
is in preparation to support fixed function GL calls for vertexless
shaders.

File src/gpu/gl/GrGpuGL.h (right):

https://codereview.chromium.org/23636011/diff/1/src/gpu/gl/GrGpuGL.h#newcode34
src/gpu/gl/GrGpuGL.h:34: const GrGLContextInfo& ctxInfo() const { return
fGLContext.info(); }
We could avoid having to add this getter by sending the GrGpuGL to
GrGLShaderBuilder, but that would entail several changes to the shader builder
as well as changing a few utility functions in different files.
