Adjust default prefix keys; advice x-create-frame

* exwm-input.el (exwm-input--on-KeyPress-line-mode, exwm-input-prefix-keys):
  Allow users to disable 'C-c' prefixed keys; Add 'C-c' to / remove 'M-!'
  from the default prefix keys.

* exwm-workspace.el (exwm-workspace--x-create-frame, exwm-workspace--init):
  Advice `x-create-frame' to prevent it from hanging EXWM, making e.g.
  speedbar working.
* exwm-floating.el (exwm-floating--set-floating): Remove the now unnecessary
  request that sets override-redirect on floating frames.
