Subject: vo_opengl: add mechanism to retrieve Display from EGL context

The VAAPI EGL interop code will need access to the X11 Display. While
GLX could return it from the current GLX context, EGL has no such
mechanism. (At least no standard one supported by all implementations.)
So mpv makes up such a mechanism.

For internal purposes, this is very rather awkward solution, but it's
needed for libmpv anyway.
