mac80211: move txrate_idx into RC algorithms

The sta_info->txrate_idx member isn't used by all RC algorithms
in the way it was intended to be used, move it into those that
require it (only PID) and keep track in the core code of which
rate was last used for reporting to userspace and the mesh MLME.
