Upstream service worker "unregister" tests to WPT

Upstream service worker "unregister" tests to WPT

**unregister-controller**

The Chromium version of this test is equivalent to the version available
in the Web Platform Tests project and may therefore be removed without
impacting coverage (along with its associated "resource" file).

**unregister-then-register-new-script**

The Chromium version of this test is equivalent to the version available
in the Web Platform Tests project and may therefore be removed without
impacting coverage. Remove the associated "resource" file from the
Chromium project because it is no longer referenced by any tests.

**unregister-then-register**

The Chromium version of this test is largely equivalent to the version
available in the Web Platform Tests project and may therefore be removed
without impacting coverage. The Chromium includes an additional
sub-test, however. Extend the Web Platform Test version with this
additional sub-test.

Remove an irrelevant comment that describes a possible extension to the
test (although the referenced object equality is expected in some
contexts, it is not expected in the associated sub-test because the
relevant objects are created in distinct JavaScript realms).

**unregister**

The Chromium version of this test is equivalent to the version available
in the Web Platform Tests project and may therefore be removed without
impacting coverage.
