form rule for membership price set when using auto-renewal option

related to #CRM-10370

if a membership price set field option value references a membership type that had auto-renew enabled, the auto-renew functionality is ignored.

until the core issue is fixed, we should add a form rule at the price set field level:

• if membership type auto-renew = required > prevent the inclusion of that field if another membership type is also enabled via a field option
• if membership type auto-renew = optional > return message warning that the auto-renew function will not work.
