  [WPE][GStreamer] support auto-pluging of different sinks
https://bugs.webkit.org/show_bug.cgi?id=256482

Reviewed by Xabier Rodriguez-Calvar.

This solves several cases:

- secondary (video only/pip) playback: audio sink allocates resources in
ready state (as part of auto audio sink detection), which interferes
with the main playback.

- "external" playback, or playback with other sink elements: in this
case we want playbin2 to autoplug needed elements.
