Allow showing buffers on other workspaces and moving an X window by switching

Browse source 
to its buffer

* exwm-workspace.el (exwm-workspace-show-all-buffers, exwm-workspace-switch)
  (exwm-workspace-move-window, exwm-workspace-switch-to-buffer): Show buffers
  on other workspaces if `exwm-workspace-show-all-buffers' is non-nil.

* exwm-layout.el (exwm-layout-show-all-buffers, exwm-layout--refresh): Allow
  moving an X window by switch to its corresponding buffer from another
  workspace when `exwm-layout-show-all-buffers' is non-nil.
* exwm.el (exwm--ido-buffer-window-other-frame): Handle the case when
  `exwm-layout-show-all-buffers' is non-nil.

* exwm-floating.el (exwm-floating--set-floating): Handle the case when
  *scratch* buffer is killed.

* exwm-workspace.el (exwm-workspace-switch-to-buffer): Renamed from
  `exwm-workspace-switch-to-window' to better reflect its role.
