Import webvtt/parsing WPT
https://bugs.webkit.org/show_bug.cgi?id=261671

Reviewed by Eric Carlson.

Upstream commit: web-platform-tests/wpt@46b2968

Thanks to the work done in https://bugs.webkit.org/show_bug.cgi?id=261460,
we can run WPT for WebVTT in WebKitTestRunner. So we can import them from
the upstream and remove the duplicate tests copied to
/LayoutTests/media/track/opera/track/webvtt/parsing.

Additionally, the WebKitTestRunner has been updated to fix flakiness that
occurs when running tests in parallel. This is achieved by ensuring that
the caption mode is set to testing mode before setting the caption display mode.
