iwlwifi: mvm: implement UMAC scan API
This API uses second CPU scan commands, and can support multiple
simultaneous scans.
Adding the new API, and adding new mechanisms to deal with up to
8 simultaneous scans instead of the old scan status.
New scan API requires scan configuration for default scan parameters,
adding it in _up flow. Also updating scan configuration after updating
valid scan antennas via debugfs.
