Expand SkImage::getTextureHandle call

AFAICT cc/output/gl_renderer.cc only calls SkImage:getTexture to determine the origin of the backing GrTexture. What do y'all think of this CL as a means of removing that call to getTexture?

One alternative would be to add a new entry point like:

bool SkImage::getBackendTextureDesc(GrBackendTextureDesc* desc) const;

which fills in the entire desc and returns whether the image is texture backed.
