x11: Add x11_window_show()

This is an incremental step towards the implementation of
waffle_window_show().

In order to prevent regressions, the behavior of x11_window_create() is
preserved until the implementation of waffle_window_show() is complete for
the X11 platforms. That is, x11_window_create() still shows the window.
