Add QCA vendor attributes for measurement frequency for FTM/AOA

Browse source 
Add attributes for specifing the frequency where FTM/AOA measurement is
done over the air. This allows the user space framework to maintain its
own cache of peers without depending on the kernel scan results cache,
or perform scans less often (since entries in the kernel scan results
cache expire quickly). The change is backward compatible. If the
frequency attribute is not specified, the kernel scan results cache will
be queried, like done today.
