Add missing MediaController API feature (mdn#21039)

* Add missing MediaController API feature

This PR is a part of a project to add missing interfaces and interface features to BCD that are from an active spec (including WICG specs) and is supported in at least one browser. This particular PR adds the missing `MediaController` API. The data comes from the [mdn-bcd-collector](https://mdn-bcd-collector.gooborg.com) project (v10.2.10).

Tests Used: https://mdn-bcd-collector.gooborg.com/tests/api/MediaController

Additional Notes: While the feature was removed from the spec (see whatwg/html#1225), we still currently document HTMLMediaElement.controller, which returns this interface, so I figured it would be sensible to add this to BCD.
