[canvaskit] Add test for MakeImageSnapshot using WebGL surface

This test shows how to turn a SkPicture into a portable
SkImage, even if that SkPicture has an SkImage that is
backed by a LazyImageFromTextureSource.

Without the extra readPixels call, the result of
makeImageSnapshot() will have SkImages backed by textures
belonging to the temporary WebGLCanvasSurface and
not be portable.
