layout: Refactor to support window decorations, add border and fullscreen backdrop

Windows are now wrapped in Tiles, which keep track of window-specific
decorations. Particularly, I implemented a black fullscreen backdrop,
which finally brings fullscreened windows smaller than the screen in
line with how the Wayland protocol says they should look—centered in a
black rectangle. I also implemented window borders, which are similar to
the focus ring, but always visible (and hence affect the layout and
sizing).
