New Wifi Metrics Connection Event logging

Created a new StaEventList which logs all commands & messages from
Supplicant, Framework and the API that can modify the state of a STA
connection. Upto 512 of these are listed atomically and added to the
WifiMetrics report.

This enables metrics about the full lifetime of a Connection.
