  Context: Remove mutable gl::State getter.
  
  This will preserve layering - the API layer doesn't mutate the state
  directly, it passes the API call through to the Context. Is also
  removes the possiblity of any shenanigans of the Validation layer
  changing the GL state.
  
  Also, this CL refactors a few validation entry points to take
  ValidationContext instead of Context. ValidationContext will be the
  correct way to interact with the gl::Context in the Validation code.
  
  Finally, additional refactorings make ContextState a proper class with
  private data. This allows the ContextState itself to keep a mutable
  pointer to the gl::State, so ValidationContext can modify it if
  necessary (and it will be necessary for Framebuffer completeness
  caching).
