rtw88: add path diversity
This feature chooses to transmit with antenna that has better signal
strength periodically under 1ss rate.
It can benefit connection quality in the following cases:
1. User is far away from the AP.
2. The far-field pattern of the antenna showed significant signal
strength difference.
