Revert "Remove origin field from GrSurface"

This reverts commit df0e09feacb29290fe94d37f921731b18f2edae0.

Reason for revert: Experimental revert to see if this is blocking the roll


Original change's description:
> Remove origin field from GrSurface
> 
> This mainly consists of rm origin from GrSurface and the wrapBackEnd*
> methods and then re-adding an explicit origin parameter to all the 
> GrGpu methods that need it.
