wifi: rtw89: introduce v1 format of firmware header

New firmware header is used by upcoming WiFi 7 chips to have more
information, so use common field w3[31:24] to determine header version,
and then use corresponding function to read firmware version and commit ID:

rtw89_8852be 0000:03:00.0: Firmware version 0.29.29.1 (799134c3), cmd version 1, type 5
rtw89_8852be 0000:03:00.0: Firmware version 0.29.29.1 (799134c3), cmd version 1, type 3
