Coexist: fix some coexist bugs

1. Fix high beacon and broadcast packets loss ratio of WiFi to make
   MDNS test pass.
2. Improve stability of WiFi performance with a little
   sacrifice of throughput.
3. Improve BLE advertising and connection performance with dynamic
   priority. It sacrifices a little WiFi throughput, but achieves balance
   between WiFi and Bluetooth.
4. fix bug bb reset lock flag to avoid bb reset lock unhandle
5. fix bug wifi reset mac cause task watch dog timeout
6. fix bug wifi reset mac position
