Focus workspace frames upon _NET_ACTIVE_WINDOW

Browse source 
* exwm.el (exwm--on-ClientMessage): Take care of focusing
workspace frames when a _NET_ACTIVE_WINDOW message is received for
a workspace frame.  This is responsibility of the window manager
when it advertises _NET_ACTIVE_WINDOW support, which we do.
Emacs versions before 29 took care of setting the input focus to
the frame.

Thanks-to: Po Lu for the work on Emacs and assistance with this
           issue.
