Add '[SecureContext]` tags to the interface

[OnkarRuikar]

• Related to Extract 'SecureContext' status in json files webref#1142 (comment)

w3c/webref repo automatically extracts syntaxes from these spec docs. At the moment some syntax sections are missing the [SecureContext] tags so it is missing from extracted data in webref as well.

The feature has been marked available in secure context in MDN docs.

The PR adds the tags to the ContactAddress interface.

Yeah, this seems like an oversight. @beverloo ?

Just confirming that WebKit already has this as SecureContext, and so does chrome:

@OnkarRuikar, please make sure you fix the bug in your script for adding SecureContext to partial interfaces ... that's going to break a lot of specs if people merge those PRs. I think Webidl2.js might catch those, but I don't know about BikeShed.

PS, @OnkarRuikar, the commit message should be "Add [SecureContext] extended attribute to X interface" or similar.
