Revert of Cleanup of shader building system

Revert of Cleanup of shader building system (patchset #25 id:470001 of https://codereview.chromium.org/611653002/)

Reason for revert:
Seems to have messed up windows 7 gms

Original issue's description:
> Cleanup of shader building system
> 
> this is a huge refactor and cleanup of the gl shader building system in
> Skia.  The entire shader building pipeline is now part of
> GrGLProgramCreator, which takes a gp, and some fps, and creates a
> program.  I added some subclasses of GrGLProgram to handle the
> eccentricities of Nvpr/Nvpres.  Outside of the builders folder
> and GrGLPrograms, this change is basically just a rename
> 
> 
> solo gp
