Xia Xiaotian f16b635326 add coex API to enable BLE connection dynamic priority(0fcfa554) ...

update libphy.a to v4181 for ESP32(c4ea2b3c)

    1. add API void set_rx_sense(sint8 sense_thr)
    2. optimize RXIQ calibration
    3. add i2c master reset to avoid failing to restart when i2c exception happens
    4. add disable_wifi_agc before close rf
    5. if wifi switch channel at BT on mode, do not switch hardware channel, just configure register
    6. do not configure bb i2c every time to avoid disturb BT. Only configure bb i2c when switch between 20M and 40M
    7. optimize some txrf registers to make TX mask better
    8. do not switch channel in phy force wifi chan, let hardware to do it
