https://bugs.webkit.org/show_bug.cgi?id=261671

Reviewed by Tim Nguyen.

Upstream commit: web-platform-tests/wpt@6bb6c31

Timeout issue is fixed in https://bugs.webkit.org/show_bug.cgi?id=262680,
so we can import the tests for webvtt/parsing now. And we can also remove
the duplicate tests copied to /LayoutTests/media/track/opera/track/webvtt
