[GTK][WPE] Skia Compositor: use SkCanvas::clipShader for image masks instead
of intermediate surface
https://bugs.webkit.org/show_bug.cgi?id=312557
Reviewed by Nikolas Zimmermann.
Not only we avoid the intermediate surface creation, we can paint the
mask image only once with no transforms, and then create a SkShader from
the cached image for the current transform.
