Add support for the PostgresSQL ts_rank_cd function

Description

The ts_rank_cd function is used as an alternative to ts_rank for penalizing query words that are further apart from each other.

I'm thinking that adding a cover_density parameter to SearchRank should be enough. If this parameter is set to True the function will be switched to ts_rank_cd.

Almost a duplicate of #28194. However, #28194 also suggests adding the normalization keyword parameter. Should we keep both tickets and address both issues separately?

I guess we could close this one as duplicate of #28194 and have ​https://github.com/django/django/pull/12597 address both.

Is it something you're interested in doing Hannes?

I don’t know how I missed that ticket. Sorry about that!

Sure, let’s close this ticket in favor of #28194. I’ll update my PR to add support for the normalization parameter.
