This is again a grab interface that mostly wants to meddle with focus,
logically setting a NULL surface if the surface client does not match
the popup client.
Since popups are meant to naturally work with any input device, the
code has been refactored to not involve the MetaWaylandPointer directly
in MetaWaylandPopup creation or getting the top popup surface (memory
management was shuffled), or compressing multiple grabbing xdg_popups
together (the existing grab maintains a single MetaWaylandEventHandler
for all).
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3420>
The order and way include macros were structured was chaotic, with no
real common thread between files. Try to tidy up the mess with some
common scheme, to make things look less messy.
Add a bridge between the MetaWaylandPopup object and the corresponding
popup surface role. This bridge replaces communicating dismissed and
unmapped popup events.

If a client creates an xdg_popup given a parent that is a xdg_popup that
is not the most top one in the grab chain, send the
not_the_topmost_popup error.
Also fail a client who destroys a popup that is not the top most one.

We'll want to expose popup logic outside of meta-wayland-pointer.c and
one day we'll also probably want to add touch support for popups, so
lets move it to its own file. There are no significant semantical
changes, only refactoring.
