Change input mode of window being clicked

Browse source 
When clicking a mode-line of other window to switch the EXWM input
mode, `window-buffer' does not return the window whose mode-line has
been clicked, but the current one.  This change ensures that the right
window has its input mode and mode-line updated.

* exwm-input.el (exwm-input--update-mode-line): Factor out setting
`mode-line-process'.
(exwm-input--grab-keyboard, exwm-input--release-keyboard)
(exwm-input-grab-keyboard, exwm-input-release-keyboard): Make sure
the buffer of the window being clicked has its input mode updated.
