Auto merge of #23351 - CYBAI:fix-modes, r=nox

Fix modes for fetching classic worker script and introduce parser metadata for request

While reading [the spec](https://html.spec.whatwg.org/multipage/#fetch-a-classic-worker-script) for `fetch a classic worker script`, I found the `mode` and `credential-mode` are opposite to the spec. So, the first commit will fix it.

Also, I found there's a `parser metadata` for `request` so I tried to introduce it in this PR as well.

For WPT, I found there's a `/workers/constructors/Worker/same-origin.html` which was disabled in  #3180. We pass most of the tests now.
