Service Worker: Add WPT to check if `client.url` is a blob URL

This CL adds a WPT to check if `client.url` of a blob URL worker is a blob URL. The test succeeds when the PlzDedicatedWorker feature is enabled.

+This is a testharness.js-based test.
+FAIL Client.url of a blob URL worker should be a blob URL. assert_not_equals: worker client should exist got disallowed value "one worker client should exist"
