    bhyve nvme: Advertise Namespace changed AEN
    
    Advertise Namespace Attribute Notices events in the Optional
    Asynchronous Events Supported (OAES) field of the Identify Controller
    data structure. Additionally, rename the enums and macros to clarify
    these are AEN's related to Notices and not generic information.
