LibWeb: Add basic "top layer" support

Browse source 
Implements the "top layer" concept from "CSS Positioned Layout Module
Level 4" specification.

- The tree builder is modified to ensure that layout nodes created by
  top layer elements are children of the viewport.
- Implements missing steps in `showModal()` to add an element top top
  layer.
- Implements missing steps in `close()` to remove an element from top
  layer.

Further steps could be:
- Add support for `::backdrop` pseudo-element.
- Implement the "inert" concept from HTML spec to block hit-testing
  when element from top layer is displayed.
