iwlwifi: add vendor specific capabilities for some RFs
On some RFs we want to advertise vendor specific capabilities to indicate support for improved beamforming rates and/or on 160 MHz, some APs where Intel has collaborated with the vendor will use it to improve behaviour. Add these elements where relevant, i.e. for HR and GF RFs.
