Upstream service worker `fetch` test to WPT
**fetch-request-html-imports**
Use HTTPS version of absolute URLs and schedule iframe element to be
removed at the completion of the test.
**fetch-request-resources**
Extend the WPT version of this test with the novel aspects of the
Chromium version:
- assertions for the `redirect` attribute of the Request object
- 1 additional test case for image resource requests
- 2 additional test cases for stylesheet resource requests
- 15 test cases for "fetch" requests
- 6 test cases for audio resource requests
Note that while the Chromium version also contains test cases for image
resources loaded via CSS, equivalent tests are already present upstream
(under the name `fetch-request-css-images.https.html`) and therefore do
not need to be migrated.
Chromium continues to fail the upstream version due to its additional
assertions for the `integrity` attribute of the Request object. Due to
this, it cannot be used as a substitute for the Chromium-specific
version. Persist the Chromium-specific version under a new file name
documenting its deprecated status.
