Allow apex packages to be signed with key that has rollback capability
When a key is rotated with a new key, it may continue to trust the old
one. As such, trusted old key should be able to update.
We no longer need to handle "key-downgrade" separately in any situation.
An update will be installed iff it is signed by a trusted key (even
during Rollbacks/Downgrades).
