esp_bt_sleep_disable() function

- ESP_OK: Success - ESP_ERR_INVALID_STATE: Invalid Bluetooth Controller state - ESP_ERR_NOT_SUPPORTED: The modem sleep mode is not supported

1. Bluetooth Controller will not be allowed to enter modem sleep after calling this function. 2. In ORIG modem sleep mode, calling this function may not immediately wake up the Controller if it is currently dormant.
