Subject: 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)
