Add sameSiteCookies option to SharedWorker options

[arichiv]

Description

This is the second of 3 PRs adding spec changes from https://privacycg.github.io/saa-non-cookie-storage/ launching in Chrome 125.

Motivation

sameSiteCookies is a new option for SharedWorker construction that allows a given worker to be restricted to SameSite=None cookies even when created in a first-party context. This is important as only workers without access to SameSite=Lax and SameSite=Strict cookies can be accessed via requestStorageAccess.

@sideshowbarker I noticed the new spec I added shows up as 'unknown' and the older spec that was listed (for SharedWorker) is gone now. Is there a way I could restore the old (default) spec and list the new one alongside it with a name?

I'm okay with this as is, how do I follow up to add compat information for sameSiteCookies? It's Chrome 125+ only right now

Yes, the way to do that is to edit the file at https://github.com/mdn/browser-compat-data/blob/3bfaadfe0e5f56016ef782c5247f0cfc5a4dfada/api/SharedWorker.json#L67 and change the spec_url value there to an array that includes/adds any additional spec URLs.

That’d need to go somewhere in the data at https://github.com/mdn/browser-compat-data/blob/3bfaadfe0e5f56016ef782c5247f0cfc5a4dfada/api/SharedWorker.json#L63
