wifi: rtw89: support firmware log with formatted text
Original firmware log which is sent via C2H message bloats
code size of firmware and is also length-limited. So we put
some common log into format file, and firmware could use a
log ID and some variables in C2H message to map a formatted
text via pre-designed rule.
