[PW_SID:1125009] [1/3] station: Add Utilization/SNR/LastSeen to station diagnostics

[IWDTestBot]

For metric gathering and general debugging its convenient to query
the last known utilization and/or SNR from the currently connected
BSS. In addition another property was added, "BssLastSeen" which is
the seconds since the last scan returned the BSS. Since the
BSS's beacon info (like utilization/SNR) are only updated upon
getting scan results we need to also advertise the "age" of the
data so any consumers can decide whether or not to ignore these
values if they are too old.
