[visionOS] Add support for RemoteEffects based OverlayRegions
https://bugs.webkit.org/show_bug.cgi?id=307059
<rdar://163353038>
Reviewed by Mike Wyrzykowski.
Add support for new Remote Effect based Overlay Regions behind a compile
time flag.
Instead of doing big tree traversals after each rendering update, this
API let's us use clearer signals:
- EventRegion changes (setEventRegion)
- VisibleRect changes (visibleRectChangedForOverlayRegions)
- RLT hierarchy changes (updateOverlayRegionAfterHierarchyChange)
- Sticky nodes begin/end sticking
(stickyScrollingTreeNodeBeganSticking/EndedSticking)
- Fixed/sticky nodes added/removed (fixedOrStickyScrollingTreeNodeWillBeRemoved)
It also removes the need for doing coordinate space conversions and
clipping on our end!
