Fix various issues with multi-monitor support

* exwm-workspace.el (exwm-workspace-switch): Do not hide X windows
when switching to a workspace on another output; update the
timestamp (last switched to) of a workspace frame.
(exwm-workspace-move-window): Do not hide an X window when moving it
to an active workspace on another output.

* exwm-floating.el (exwm-floating--set-floating):
* exwm-layout.el (exwm-layout-set-fullscreen):
* exwm-manage.el (exwm-manage--manage-window)
(exwm-manage--on-ConfigureRequest):
* exwm-systemtray.el (exwm-systemtray--refresh)
(exwm-systemtray--init):
Correct coordinate calculations.

* exwm-workspace.el (exwm-workspace--current-width): Removed since no
longer used.
