wifi: rtw89: indicate TX power by rate table inside RFE parameter

For next-generation chips, TX power by rate table comes from RFE (RF
front end) parameter. It can be different according to RFE type. So,
we indicate TX power by rate table inside RFE parameter ahead. For
current chips, even with different RFE types, a chip is configured
with a single TX power by rate table. So, this commit doesn't really
affect these currently supported chips.
