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.

Support WorkerOptions for Worker
I'd like to start working on updating SW related codes and I found it will have some algorithms related to module workers. And I found parts of the spec update is related to [fetch a module worker script graph](https://html.spec.whatwg.org/multipage/#fetch-a-module-worker-script-tree), maybe it's worth being a separate PR?

Receive streams in WebRTC (and MediaStreamTrack support)
This adds the `ontrack` event handler to webrtc, and all the `MediaStreamTrack` stuff necessary to make it work.
WebRTC has the ability to group media tracks into streams using MSIDs, but I haven't yet figured out how to do this. For now, `ontrack` should work.
This _should_ be complete, but it hasn't yet been tested (hence the WIP)

Remove mozjs dep from malloc_size_of.
This makes making local changes to mozjs_sys much more frustrating than it should be, and blocks merging #22130.

Now servo/media player requires a new parameter for its creator, which
is a trait object that provides the GL parameters needed for setup the
generation of frames as GL textures.
This patch provides a dummy GL context trait object where the code
path will go to the default of raw frames.
Webaudio test expectation also were changed, adding two new failing
tests.
