Platforms implementing WebSocketTask pass hybi/close-and-server-script-exception-expected.txt
https://bugs.webkit.org/show_bug.cgi?id=237727

Reviewed by Alex Christensen.

The root expected.txt had a line with FAIL but all platforms that implement WebSocketTask
PASS the test fully. Make this the default and remove redundant expectations and add a
FAIL for Apple WebKitLegacy ports which don't implement WebSocketTask.
