Fix problems with active minibuffer

* exwm-floating.el (exwm-floating--unset-floating): Never use the
minibuffer window to display an `exwm-mode' buffer.

* exwm-input.el (exwm-input--on-buffer-list-update)
(exwm-input--update-focus): Allow updating input focus when the
minibuffer is active.
(exwm-input--update-focus): Handle the case when an auto-hiding
minibuffer is active.
(exwm-input--during-key-sequence): Renamed to
`exwm-input--line-mode-passthrough'.
(exwm-input--line-mode-passthrough): New variable for forcing all events
to be passed to Emacs in line-mode.
(exwm-input--on-KeyPress-line-mode, exwm-input-send-next-key): Use it.
(exwm-input--finish-key-sequence, exwm-input--init, exwm-input--exit):
Drop `exwm-input--finish-key-sequence'.
(exwm-input--line-mode-cache): New variable for caching incomplete key
sequences.
(exwm-input--cache-event): New function for handling new key events.
(exwm-input--on-KeyPress-line-mode, exwm-input--on-KeyPress-char-mode):
Use it.
