rtw89: extend firmware commands on states of sta_assoc and sta_disconnect

The h2c_join firmware command is used to indicate a station is connected,
and the assoc_cmac_tbl firmware command is used to set CMAC table
corresponding to a mac_id. Both commands must work in both station and AP
modes. Use the mac_id of rtw89_sta naturally and intuitively.
