wifi: rtw89: consider ER SU as a TX capability

ER (Extended Range) SU is to have a larger coverage. We set this as a RA
capability, and then firmware can choose ER SU to transmit packets to
reception at cell edge. For 8852C, it needs to fill this capability in
TXWD, so update rtw89_build_txwd_info0_v1().
