overlay: add snap-to-edge overlay (PR #1652)

...and unify region overlay and snap-to-edge overlay into overlay.c.

Snap-to-edge overlay is delayed for 500ms to prevent flickering when
the view is dragged from an output to another (demo in discussion labwc#1613).

This also fixes a bug that region overlay is not shown when a modifier
key is re-pressed.
