Add Customize interface for simulation keys

* exwm-input.el (exwm-input-simulation-keys): New user option for
setting simulation keys.
(exwm-input--init): Initialize simulation keys from this variable.

* exwm-input.el (exwm-input--simulation-prefix-keys)
(exwm-input--on-KeyPress-line-mode)
(exwm-input--update-simulation-prefix-keys)
(exwm-input-set-simulation-keys, exwm-input-set-local-simulation-keys)
(exwm-input-send-simulation-key): `exwm-input--simulation-keys' is now
a hash table storing both simulation keys and prefix keys.
(exwm-input--unset-simulation-keys): Clear the hash table.
(exwm-input--exit): Use `exwm-input--unset-simulation-keys'.
* exwm-core.el (exwm--kmacro-map, exwm-mode-menu): Adapt to the
change of `exwm-input--simulation-keys'.

* exwm-config.el (exwm-config-default): Update the example.
