Autoplay Policy Detection API accessibility self-review

[chrisn]

Most of the FAST checklist items do not apply.

The API does enable a content fallback mechanism, in that if a website uses the API to determine that auto-playing media is blocked, the website can choose to show alternative media instead.

From the MAUR checklist, it seems that those requirements apply to content authors rather than this API.
