Upstream service worker tests to WPT
**install-event-type-worker**
This test is nearly identical to the version available in the Web
Platform Tests project. Update the upstream version with the only
meaningful difference between the tests: an additional assertion for the
event object provided to the service worker's `oninstall` event handler.
Extend assertions with description strings to aid debugging in case of
test failure.
**interfaces**
Extend the upstream version with the additional assertions found in the
Chromium-specific version. Remove the Chromium-specific version.
Re-locate the associated "resource" file as it is reference by
unrelated tests.
**invalid-blobtype**
Remove the Chromium-specific version because it is equivalent to the
upstream version. Simplify script resource URLs in the upstream version.
**invalid-header**
Remove the Chromium-specific version because it is equivalent to the
upstream version. Simplify script resource URLs in the upstream version.
**multiple-register**
Remove the Chromium-specific version because it is equivalent to the
upstream version. Correct a typo in an assertion message in the upstream
version.
