[jfx17u] RFR: 8336940: Update GStreamer to 1.24.6

[Johan Vos]

Almost clean backport of https://github.com/openjdk/jfx/commit/b88ac0495650bd033ba11e3131e9bffc517872eb

There are 2 manual changes:
1. modules/javafx.media/src/main/native/gstreamer/gstreamer-lite/gst-plugins-good/gst/audioparsers/gstaacparse.c is not part of jfx17u
2. modules/javafx.media/src/main/native/gstreamer/gstreamer-lite/gst-plugins-good/gst/isomp4/qtdemux.c had a merge conflict, since jfx17u doesn't have JDK-8277309
3.
