Add stubbed out GrContext

This CL mainly just:
   stores the GrContextOptions in GrContextThreadSafeProxy (so they can be passed on to a stubbed out GrContext)
   adds a method to create a stubbed out GrContext that has a GrStubGpu
      - the stubbed out GrContext isn't quite ready for prime time yet
