[1/7] band: introduce new method of tracking frequencies

Commit Message

Currently the wiphy object keeps track of supported and disabled
frequencies as two separate scan_freq_set's. This is very expensive
and limiting since we have to add more sets in order to track
additional frequency flags (no-IR, no-HT, no-HE etc).

Instead we can refactor how frequencies are stored. They will now
be part of the band object and stored as a uint16_t array where
each index corresponds to a channel, and the value will contain
various flags for that frequency.
