[IMP] account_payment: add hook method

I create a method `_prepare_payment_display_name` for inherit.
When you want to set a new name for payment, you can extend this method.

Exp:
I create a new partner type is `employee` in payment for payment with
employee, but with your old code i can't add the key `outbound-employee`
or `inbound-employee`. So, the system will give an error message.

I think if you add this hook method, it will be good for customizers.

closes odoo/odoo#85251
