This commit updates Meta/import-webkit-regexp-tests.py and re-imports WebKit tests. Removed pcre-test-1 from SKIP_TESTS because we pass it. Removed everything except slow.js from XFAIL_TESTS. We pass everything except slow.js, which still hits the step limit. Moved overflow.js to SKIP_FILES because it tests WebKit's behaviour of rejecting regexps with huge quantifiers. Ladybird, Chrome, and Firefox just clamp them.
