  [GStreamer] Harness: Refactor output stream handling in preparation for "sometimes" pad support
https://bugs.webkit.org/show_bug.cgi?id=250757

Reviewed by Xabier Rodriguez-Calvar.

The harnessed output stream (corresponding to the element source pad) is now managed through a
dedicated Stream class embedded in the GStreamerElementHarness scope. This new architecture will be
useful for the upcoming support for "sometimes" src pads where the harness will be able to work on
auto-plugger elements such as parsebin and decodebin(3).

No change in functionality, covered by existing API and WebCodecs layout tests.
