Revert "Add a deferred copy surface"

This reverts commit 4431de6af930a8638c194b072558ea3a4b79d908.

Reason for revert: ANGLE errors (at the very least)

Original change's description:
> Add a deferred copy surface
> 
> This CL forces all GrSurface copies to go through a GrSurfaceContext (rather than GrContext).
> 
> There is a bit of goofiness going on here until read/writePixels is also consolidated in GrSurfaceContext and a proxy-backed SkImage/SkSurface is added.
>
