Subject: MakeBackendTextureFromSkImage

Creates a static function on SkImage which converts the SkImage to a
GrBackendTexture. The texture is unowned by Skia, and must be deleted
by the caller. Allows for a no-copy / no-conversion fast path if the
provided image is unowned (unique()) and texture backed.
