WebGPU - Add secure context info

[hamishwillee]

This adds WebGPU to the list of APIs that require a secure context, and also adds the secure-context header to the API page.

May not be necessary, but I also added a "Security Requirement" section that reflects this same information. Trying to do the right thing for the future.

@Elchi3 @chrisdavidmills Appreciate your comments.

Other FF113 docs work for this can be tracked in #26157

Looking good, apart from one comment.

I like the idea of just adding the banner to the main API page; I kind of ignored it originally, because I thought adding it to all the pages was a bit to obtrusive.

Thanks both, looks great to me! 👍

@chrisdavidmills Yes, the rule is to the main API page. If there is a gating accessor method/property I sometimes add it there too - because that is where people will discover it. But otherwise adding everywhere is frowned upon.

That said I hope one day we automate getting the context metadata automatically, apply it to all pages where it is relevant, and have a much smaller icon to indicate that secure context applies
