wifi: mt76: mt762x: extend mt76_connac_mcu_sta_basic_tlv for per-link STA

Extend mt76_connac_mcu_sta_basic_tlv with the per-link STA configuration.

The patch we created is a prerequisite to enable the MLO function in the
driver. It is purely a refactoring patch so the functionality should
remain unchanged.
