baohongde 78ecc043d5 Improve coexistence performance according to specific WiFi/BT/BLE scienario
1. Improve WiFi performance in some Classic BT scienario(idle, inquire scan,
       connecting, connected, sniff, a2dp pause, etc).

    2. Support WiFi + Classic BT + BLE mesh coexistence scienario.

    3. Improve WiFi scan and connect performance in coexistence scienario.
