  [GStreamer][MSE] Avoid adding redundant tracks to MediaPlayer
https://bugs.webkit.org/show_bug.cgi?id=288974

Reviewed by Alicia Boya Garcia.

In MSE, WebKit already adds tracks to the HTMLMediaElement and the SourceBuffer in
SourceBuffer::sourceBufferPrivateDidReceiveInitializationSegment, so we need to
avoid adding each Track again in updateTracks.

* LayoutTests/media/media-source/media-source-vttsimple.html: Explicitly test for the number of tracks.
* LayoutTests/media/media-source/media-source-webm-expected.txt:
* LayoutTests/media/media-source/media-source-webm.html: Ditto.
* Source/WebCore/platform/graphics/gstreamer/MediaPlayerPrivateGStreamer.cpp:
(WebCore::MediaPlayerPrivateGStreamer::updateTracks): Don't add Tracks to MediaPlayer if in MSE.
