[WPT] Reland with fix: Test script's base URL used in dynamic imports

This CL checks base URL used in resolving relative URL-like
specifiers in dynamic imports() from

- `<script>`s,
- worker top-level scripts, and
- worker scripts imported by `importScripts()`.

This is for whatwg/html#5751.

This CL relands
https://chromium-review.googlesource.com/c/chromium/src/+/2198835/
with a fix:

`base-url-worker.sub.html` was flaky due to
race between two `fetch_tests_from_worker()`s.
In this reland, a `fetch_tests_from_worker()` is
moved to a new file `base-url-worker-importScripts.html`,
having at most one `fetch_tests_from_worker()` per file.
