include: mailbox: Update RPMI notification structs and add performance events

Browse Source 
Add rpmi_event_notification_state enum with disable, enable, and return
current state IDs. Also, add req_state field to rpmi_enable_notification_req
and current_state field to rpmi_enable_notification_resp for RPMI specification
compliance.

Add notification event ID enum and data structures for RPMI Performance
service group events: power change, limit change, and level change.
