Description

Chrome 142 adds support for interest invokers: see https://chromestatus.com/feature/4530756656562176.

This PR aims to document all features of interest invokers. Specifically, it will add:

A listing of all the interest invoker features on the popover API landing page (it really feels like it is part of this API, although I appreciate it has use cases outside popovers). If this isn't appropriate, I can quite easily separate it out.
An interest invokers guide.
Reference pages for the interestfor attribute, which is available on the <a>, <button>, <area>, and SVG <a> elements.
A ref page for the :interest-source pseudo-class.
A ref page for the :interest-target pseudo-class.
Ref pages for the interest-delay, interest-delay-start, and interest-delay-end properties.
Ref pages for the interestForElement property, which is available on the HTMLButtonElement, HTMLAnchorElement, HTMLAreaElement, and SVGAElement interfaces.
Ref pages for the interest and loseinterest events, which are fired on the HTMLElement interface.
Ref pages for the InterestEvent interface.

Overall LGTM! This looks great to me, thanks for putting it together. I left some comments, but all of them are fairly small.
