gdk: Remove synthetic crossing event emission due to geometry changes

Browse Source 
This just applied to child windows, but now GDK should just take care of
toplevels, which shall get crossing events from the windowing when the right
conditions apply.

Removing this code fixes confused crossing state in widgets and messed up
window_under_pointer tracking (Which now is meant to be toplevels) when any
of the remaining child GdkWindows trigger these crossing events.
