Bug 1505726 [wpt PR 13980] - [media] Treat cross-origin redirect as TAINTED only for no-cors requests, a=testonly

Automatic update from web-platform-tests[media] Treat cross-origin redirect as TAINTED only for no-cors requests

With https://crrev.com/a9cbaa7a40e2b2723cfc2f266c42f4980038a949,
WebMediaPlayer blindly treats a resource experiencing cross-origin
redirects as TAINTED. In fact, it should be treated as TAINTED only
when its request mode is "no-cors".

The added tests are provided by hongchan@chromium.org.
