net80211: Radiotap: update for newer standards (add EHT, U-SIG)

iwlwifi already uses suggested EHT and U-SIG bits as well as some
more TLV bits. Update radiotap to know of those even if they might
get updated again in the future in order to get newer versions of
the driver to compile.

ath1xk drivers require further HE defines. Some of those we had
already predicted as comments in the past.
