openpgp: Introduce trait Policy. WIPfix-274

  - Add a new trait `sequoia_openpgp::Policy`.  Currently, this trait
    only has one method that returns the current time.  This time is
    used when evaluating signatures.

  - Use this trait in TPK::{revocation_status,alive,expired}.  Remove
    the corresponding *_at() functions.

  - Fixes #274.
