Emit synthetic mask for non-2d-axis aligned clip for backdrop effects

The bug case is that a clip applies to a composited backdrop effect
(backdrop-filter or mix-blend-mode), the clipping element doesn't
create an isolation group for the backdrop effect, and the clip is
not 2d-axis aligned to the containing isolation group. In the case
we need to apply the clip as a synthetic mask. (For normal non-2d-axis
aligned clip we decomposite the clip to emit a paint operation in the
composited layer for the clip.)
