Add an option to remove RRM and supported operating class indication

Browse source 
Removing radio measurements and supported operating class indication
might be needed to reduce binary size for a memory constrained system
that does not need more advanced features. However, removing these is
not recommended since they can help the AP manage the network and STA
steering.

By default this functionality is enabled.
