egl: Make sure to free the underlying egl objects when the display is freed

Browse Source 
If the display has been setup up, we should destroy the underlying
objects that the winsys has created. This can be done by calling the
winsys->destroy_display() function in _free.

Then, in that function, and for the NULL and GDL EGL platform we can
destroy the surface we have created in the setup_display() function
(through create_context()).

This allows to have clutter create a "dummy" display in
cogl_renderer_check_onscreen_template(), then free it, then recreate the
context and the surface that will be the final ones.
