corner-shape: backdrop-filter is clipped to the rounded rect, ignoring
corner-shape

Reviewed by Simon Fraser.
Give the backdrop layer its own shape path, set from the outer contour when
the corners aren't round, and drop the corners from backdropFiltersRect
so a shape reaching outside the radius isn't clipped back to it.
