Updates for Safari 17.2 beta

[Elchi3]

This PR is an experiment that helps us to understand how to automate updates to BCD whenever a browser releases a new version. (see same experiment for Firefox 120 and Chrome 120).

In the future we hope that this PR can be auto-generated. @jdatapple & @jensimmons Is this PR reviewable for you? What would you improve? Feedback on items that are not mentioned in the Safari 17.2 release notes would be appreciated. Thanks for your input which will be useful for us as we design an automated workflow. For more information about this project, see: openwebdocs/project#168.

I found these were shipped in Safari 13 and Safari for iOS 13:

• api.HTMLLinkElement.imageSrcset
• api.HTMLLinkElement.imageSizes

Cookie Store API should not be included. It is an incomplete implementation in a "testable" state. See https://bugs.webkit.org/show_bug.cgi?id=265463

These three will be included in future release notes:

• api.CanvasRenderingContext2D.reset
• api.OffscreenCanvasRenderingContext2D.reset
• api.HTMLInputElement.incremental

requestIdleCallback should not be included. It was disabled during the beta.
