net80211: migrate FC0_TYPE_MASK / FC0_SUBTYPE_MASK frame type checks to macros
* Add macros for the management and control frame type checks that
I've come across in the drivers.
* Delete some now old code (eg ath's ieee80211_is_action()) as there's now
a macro for it.
Local testing:
* not yet, I have a lot of wifi devices to find and test against
