wayland: take (visible) border width into account on configure events

Browse source 
When the compositor is asking us to resize ourselves, take
our (visible) CSD borders into account. This is similar to how we
already take the titlebar size into account.

This fixes an issue where the window size “jumps” when the user starts
an interactive resize, when csd.border-width > 0.

This as been observed in GNOME.

* Window geometry when CSDs are enabled and CSD border width set to a
non-zero value. This fixes window snapping in e.g. GNOME.
* Window size “jumping” when starting an interactive resize when CSDs
are enabled, and CSD border width set to a non-zero value.
