Description Kueno 2023-09-12 00:45:00 PDT 
As reported in https://bugs.webkit.org/show_bug.cgi?id=179370#c2, running WPT for WebVTT in run-webkit-tests results in a timeout. This is due to the caption mode of WebKitTestRunner being defaulted to `ForceOnly`, under which conditions the captions never appear. This is not a problem for LayoutTests other than WPT because we can adjust the caption mode with `window.internals.setCaptionDisplayMode('Automatic')` to ensure correct caption display during testing.

To resolve this issue, we need to make the caption mode configurable in run-webkit-tests instead of using the internal method in the window object.
