[ESP32] Release BTDM memory rather than just releasing BLE memory. (#…

…23165)

Once we are done using BLE for commissioning we should release all the
bluetooth memory. Releasing with mode ESP_BT_MODE_BLE do not release
all the memory. Releasing memory with mode ESP_BT_MODE_BLE will give us
approx. ~3K of heap onf ESP32 SOC.
