Add GrBackendTexture accessor to SkImage (take 2)
This makes accessing the GPU resource behind an SkImage a lot more typesafe. Additionally, the GrBackendObject is being deprecated so this is the path forward.
I split the controversial stuff off into https://skia-review.googlesource.com/c/skia/+/118575 (Add SkImage::setLayout call).
