gstreamer: add recipes for upstream 1.20.3 versions

oe-core has moved to gstreamer 1.22.0 and recipes which don't have
an imx version can no longer be built. Add older version of those
components to be used with the gstreamer 1.20.3.imx.

+Subject: [PATCH] libav: Fix for APNG encoder property registration
+
+The AVClass name of Animated PNG in FFmpeg 5.x is "(A)PNG"
+and it will be converted to "-a-png" through
+g_ascii_strdown() and g_strcanon(). But GLib disallow leading '-'
+character for a GType name. Strip leading '-' to workaround it.
+
+Upstream-Status: Backport [https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/2724]
