Simplify input handling

Browse source 
No functional change.

* exwm-input.el (exwm-input--current-input-mode): New function
indicating keyboard input mode.
(exwm-input--on-KeyPress, exwm-input--update-mode-line): Use
`exwm-input--current-input-mode'.
(exwm-input-grab-keyboard, exwm-input-release-keyboard)
(exwm-input--update-mode-line): Simplify.

* exwh-core.el (exwm--on-KeyPress): Remove variable, use
`exwm--keyboard-grabbed' and `exwm-input--current-input-mode'
instead.
