Fix wrong/missing ConfigureNotify events

Browse source 
* exwm-floating.el (exwm-floating--set-floating): Set exwm--floating-edges
  as absolute edges (the relative edges can be easily determined).
* exwm-layout.el (exwm-layout--show): Send correct absolute positions to
  floating X windows.

* exwm-floating.el (exwm-floating--stop-moveresize, exwm-floating-move): Send
  ConfigureNotify events after moving floating X windows.
