wifi: rtw89: coex: add v1 summary info to parse the traffic status from firmware

This debug entry is to summarize important messages to quickly address
problem types, such as firmware hang, C2H/H2C stuck, or too much
occupation of BT A2DP. If unexpected something is addressed, we can dig
the problem via other debug messages that provide more detail information.
