Monitor mlme event for wificond

1. This allows NetlinkManager to monitor MLME events.
2. This adds internal API for tracking MLME events.
3. This creates classes representing different MLME events.
4. ClientInterfaceImpl will update frequency and bssid upon
   ASSOCIATE/CONNECT/ROAM events.

Bug: 31961586
Test: compile, manual tests
