esp32: fix coex bug

    1. fix BLE connection missing in coex mode
    2. modify other parameters to make coex priority more reasonable
    3. fix modem sleep procedure trap cause Wifi disable RF when BT is
    working. Such cause that BR/EDR is difficult to be connected, BLE
    connection stability decrease and so on.
    4. modify BR/EDR coexist duration to imrove BR/EDR connect success
    ratio.
    5. Due to the hardware coexist bug, BLE scan interval/window should
    be less than 0x100(about 160ms). Therefore, it will cause BLE cannot
    scan any advertising packet while WiFi have higher priority
    behaviour(such like RX beacon, scan, TX/RX VO packets and etc.).
