core: Split x11-display initialization in 2 signals

Browse source 
We have a "setup" phase, used internally to initialize early the x11
side of things like the stack tracker, and an "opened" phase where
other upper parts may hook up to. This latter phase is delayed during
initialization so the upper parts have a change to connect to on
plugin creation.

Closes: https://gitlab.gnome.org/GNOME/mutter/issues/771
