This introduced a possible regression where the EGL display connection
could be leaked when a foreign native display (x11, wayland, etc) could
create a non-foreign EGL display that would never be destroyed.
The underlying problem needed to be solved in a different way. See
https://gitlab.freedesktop.org/gstreamer/gst-plugins-base/-/issues/640
for more details.
This reverts commit 2e686b0dad.
