Move RenderLayerCompositor's OverlapMap to its own file
https://bugs.webkit.org/show_bug.cgi?id=197915

Reviewed by Alex Christensen.

Move OverlapMap to its own file.
Make use of RectList, which was in the file but unused!
Allocate OverlapMapContainer on the heap both to avoid header pollution of internals,
and because they will get bigger in future.

No behavior change.
