Scenario is using wayland with this pipeline: videotestsrc ! glupload ! qml6glsink. First pipeline and qml construction works just fine. However if all GStreamer and QML scenegraph resources are removed, GStreamer will call eglTerminate() and sever the connection to the display server for Qt. When Qt attempts to do any further GL operations like construct a new QML scene, it can crash in any number of places as libEGL will start returning NULL or other unexpected values. What we really need is to ensure that if an external API (e.g. Qt) will eventually call eglTerminate(), there is no need for GStreamer to call eglTerminate(). This is what the foreign display flags allows setting. There is also another possible scenario where one may like to make GStreamer assume ownership of an EGLDisplay and thus eventually call `eglTerminate()`. As such, it is now also possible to mark an GstGLDisplayEGL as non-foreign. Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/8504>

A display marked as foreign will not have display global resources freed when

this display is finalized. As such, any external API using the same

`EGLDisplay` must keep the `EGLDisplay` alive while GStreamer is using any

true and a foreign #GstGLDisplayEGL must not be used after the associated

A non-foreign #GstGLDisplayEGL will destroy the associated `EGLDisplay` on

finalization. This can also be useful when a user would like GStreamer to
