 * This function first releases Controller memory by internally calling `esp_bt_controller_mem_release()`, then releases Host memory.
 *
 * If you never intend to use Bluetooth in a current boot-up cycle, calling `esp_bt_mem_release(ESP_BT_MODE_BLE)` could release the BSS and data consumed by BLE stack to heap.
 *
 * For example, if you only use Bluetooth for setting the Wi-Fi configuration, and do not use Bluetooth in the rest of the product operation,
 *  after receiving the Wi-Fi configuration, you can disable/de-init Bluetooth and release its memory.
 * Below is the sequence of APIs to be called for such scenarios:
 *
 *       esp_bluedroid_disable();
 *       esp_bluedroid_deinit();
 *       esp_bt_controller_disable();
 *       esp_bt_controller_deinit();
