Add a deferred copy surface (take 2)
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.
This is a reland of https://skia-review.googlesource.com/c/5773/ (Add a deferred copy surface)
