wifi: rtw89: read CFO from FD or preamble CFO field of phy status ie_type 1 accordingly

Add macro to get FD(frequency domain) CFO field from ie_type 1, and correct
the naming for preamble CFO field. Each IC could assign the CFO source to
either FD CFO or preamble CFO in chip_info. Based on the suggestion from HW
designer, rtw8852b and its derived versions will have better CFO tracking
performance with FD CFO.
