[GStreamer] Auto-detect USAC support via GStreamer registry
https://bugs.webkit.org/show_bug.cgi?id=314328
Reviewed by Xabier Rodriguez-Calvar.
Add a check for USAC (xHE-AAC) codec support by probing
the GStreamer registry for a decoder matching
"audio/mpeg, mpegversion=(int)4, stream-format=(string)usac".
The stream-format=usac caps field is not part of the standard GStreamer
audio/mpeg caps definition, but some custom audio sinks advertise it, so it can
be used as an indicator of USAC decoding capability.
The WEBKIT_GST_CAN_PLAY_USAC environment variable still takes
precedence as a manual override.
