wifi: rtw89: allow driver to do specific band TX for MLO

Browse Source 
For data packets that can be sent on any band, fill in main mac_id
and let HW decide. For packets that we wish to transmit on specific
band, fill in sw_mld field so HW would only send it on that band.
Main mac_id is the corresponding mac_id on band 0.
