AmbientContext (aka Ambient PCC) Framework API, with a client API for apps to subscribe for AmbientContextEvents, and a provider API for AiAi to implement and provide the detected events.

Client apps need the ACCESS_AMBIENT_CONTEXT_EVENT permission to use the service. The permission protection level is internal|role.
