Revert "Reduce dependence on GrSurface's origin field"

This reverts commit 467022b1861033d968195687da15270c208279ff.

Reason for revert: GrAHardwareBufferImageGenerator.cpp

Original change's description:
> Reduce dependence on GrSurface's origin field
> 
> Unfortunately, GrGPU and its ilk are still using the GrSurface's origin a lot. I will clean that up in a second CL.
