rtw88: coex: add debug message

Browse Source 
Add message for debugging usage and the program flow is no change.
Add a variable reserved for WLAN firmware synchronize.
Add a group of variable to save BT packet counter, it will be
assigned as mechanism judgment in the future. Now it is just for
debug usage.
