Bug 1583957 - Indicate support for autocomplete=(username|new-password|current-password). r=farre

Bug 917325 started using the `username` token.
Bug 1119063 started using the `new-password` token. This patch also adds support for `current-password` since it's the counterpart to `new-password` and we plan to use it as a signal eventually so want to encourage its use.
