Split fetch CORP tests as HTTP and HTTPS.

[youennf]

Add fetch.https.any.js in addition to fetch.any.js.
Make fetch.any.js not run in service worker.
Make fetch.https.any.js run also in service worker.
Update a test in fetch.any.js for the "same-site HTTP -> HTTPS" case.

Drive-by comment... feel free to ignore :-)

Thank you very much for putting together the PR. I can confirm that the tests pass against my Chromium WIP CL @ https://chromium-review.googlesource.com/c/chromium/src/+/1416813.

And separate thanks for having the luxury of implementing the feature with already existing test coverage . One benefit is that it prevent me from forgetting to support redirects (the last testcase in fetch.any.js fails). Thanks!

Looks great, two minor nits.

Taskcluster is failing for both Firefox and Chrome.
Looking at the logs, there does not seem to be anything suspicious related to the PR.
@foolip, any idea what this might be?

I think the problem is the change to common/get-host-info.sub.js which presumably triggers runs of lots of tests, causing the whole thing to time out.
