Remove addressee, email_greeting_id, postal_greeting_id from exposed tokens

Remove addressee, email_greeting_id, postal_greeting_id from exposed tokens

Per discussion on https://github.com/civicrm/civicrm-core/pull/19550#issuecomment-781597319
there appears to be agreement that supporting tokens like
addressee_id (which resolves to '{contact.individual_prefix}{ }.....')
should not be exposed / supported as they seem both unuseful and likely
to be breaky.

These were exposed unintentionally as part of a change to make them
available as WHERE filters on apiv3
https://github.com/civicrm/civicrm-core/commit/54e389ac6565ff534b87e5e46137a57d48d6c5c8

The discussion suggests that by contrast we should
add support to hash in the token compat subscriber
