adding content for ContentVisibilityAutoStateChangedEvent

[chrisdavidmills]

Description

This PR adds content for the ContentVisibilityAutoStateChangedEvent interface and its related event.

See my research sheet for more details: https://docs.google.com/document/d/1UobZG27MYj2jsV5m4mEAYyHbs59EJ2_3RDHuwYZLGEY/edit#

Some other notes:

1. I've added a separate page for the actual event at Web/API/contentvisibilityautostatechanged_event, as it is a global event, not attached to a specific interface (it fires on any element that has content-visibility: auto set on it). This feels weird, but I wasn't sure what else to do.
2. As a result, the sidebar was a bit weird. I've added a separate entry in GroupData.json for ContentVisibilityAutoStateChangedEvent, and used it on the event pages so at least you get a link to the event object in the side bar. But, again, it's a bit weird...

Motivation

Readers will want to know about this new API
