An overridable model method was added in a previous commit in order to neutralize a database. This commit introduce the implementation of this method for the payment modules. Also, a `_neutralize_fields` helper method is added on the PaymentAcquirer model to simplify the neutralization of the various payment modules. Part-of: odoo/odoo#67825
