Simplify and improve focus handling (#10) subtree-staging

Combine both focus update timers into one and ignore windows in "no
focus" frames.

* exwm-input.el
  (exwm-input--on-buffer-list-update):
    Avoid focusing windows in frames with the `no-accept-focus` frame
    property.
  (exwm-input--update-focus-defer-timer):
    Remove the duplicate timer.
  (exwm-input--update-focus-defer):
    Use a single `exwm-input--update-focus-timer`.
  (exwm-input--update-focus-commit):
    Read `exwm-input--update-focus-window` instead of taking a window
    as a parameter (this is what lets us combine the timers).
  (exwm-input--update-focus-commit):
    Use a let-bind instead of unwind-protect.
  (exwm-input--exit):
    Remove references to `exwm-input--update-focus-defer-timer`.
