Add support for `mouse-autoselect-window'

; This feature requires both `mouse-autoselect-window` and
; `focus-follows-mouse' being set.  Delaying autoselection is not
; supported yet.

* exwm-core.el (exwm--client-event-mask): Select the EnterNotify event
on each X window when `mouse-autoselect-window' is set.
* exwm-input.el (exwm-input--on-EnterNotify): New function for making
`mouse-autoselect-window' work on X windows.
(exwm-input--init): Listen to EnterNotify event when
`mouse-autoselect-window' is set.
