RNR: Add bss_parameters to the neighbor_db

Browse source 
Add a new field to include BSS Parameter subfield in the neighbor
database as described in IEEE Std 802.11ax-2021, Figure 9-632a (BSS
Parameters subfield format). This field holds information related to
multiple BSSID, access point co-location, and 20 TU probe response
active/inactive state.
