Issue #2472 - Part 3: Refactor Fullscreen stack to Top Layer stack

Browse source 
Fullscreen stack isn't part of the spec anymore; it's been changed to a more
generic version called Top Layer stack, which is being used by both full-screen
APIs and dialog elements.

This patch refactors it to Top Layer stack so that it can be reused for dialog
elements.

Top Layer stack spec: https://fullscreen.spec.whatwg.org/#new-stacking-layer
