Support displaying floating X windows on all workspaces

Browse source 
; Setting _NET_WM_DESKTOP to 0xffffffff makes an X windows appearing
; on all desktops (EWMH).  It's tricky to do it for tiling X windows
; so it's not implemented.

* exwm-core.el (exwm--desktop): New buffer-local variable recording
the value of _NET_WM_DESKTOP.
* exwm-layout.el (exwm-layout--hide): Do not hide X windows with this
property set to 0xffffffff.

* exwm.el (exwm--update-desktop): New function for fetching the value
of _NET_WM_DESKTOP and setting `exwm--desktop'.
* exwm-manage.el (exwm-manage--manage-window): Use it.

* exwm-workspace.el (exwm-workspace--set-desktop): Also update
`exwm--desktop'.
