When receiving Alert Message, if it is not unexpected but is unsupported for some reason, the port should return Not_Supported Message response. Also, according to PD3.0 Spec 6.5.2.1.4 Event Flags Field, the OTP/OVP/OCP flags in the Event Flags field in Status Message no longer require Get_PPS_Status Message to clear them. Thus remove it when receiving Status Message with those flags being set. In addition, add the missing AMS operations for Status Message.
