window-x11: Cleanup header and shuffle function locations

The functions meta_window_x11_create_sync_request_alarm() and
meta_window_x11_destroy_sync_request_alarm() are not used outside
MetaWindowX11 now, and don't need to be exposed in window-x11.h

Remove them from window-x11.h and shuffle these functions to
before their first usage, to avoid having to add their prototypes.
