Manually run focus-in-hook' and focus-out-hook'

Browse source 
; Since X windows are managed by EXWM, the current Emacs frame should
always be considered focused logically.

* exwm-workspace.el (exwm-workspace-switch): Manually run
`focus-in-hook' and `focus-out-hook'.
(exwm-workspace--handle-focus-in, exwm-workspace--handle-focus-out):
New functions for overriding `handle-focus-in' and `handle-focus-out'.
(exwm-workspace--init, exwm-workspace--exit): Override
`handle-focus-in' and `handle-focus-out'
