@brief Set BLE TX power for the specified Advertising or Connection handle

For the TX power type: ESP_BLE_ENHANCED_PWR_TYPE_DEFAULT, ESP_BLE_ENHANCED_PWR_TYPE_SCAN, ESP_BLE_ENHANCED_PWR_TYPE_INIT, this API will ignore the input handle number, and set 0 internally.

For the TX power type: ESP_BLE_ENHANCED_PWR_TYPE_ADV and ESP_BLE_ENHANCED_PWR_TYPE_CONN， this API will set the TX power for the target handle.

@note 1. Connection TX power should only be set after connection created.

@param[in] power_type The type of TX power @param[in] handle The handle of Advertising or Connection @param[in] power_level Power level (index) corresponding to absolute value (dBm)

@return - ESP_OK: Success - ESP_ERR_NOT_SUPPORTED: Invalid TX power type - ESP_FAIL: Failure due to other reasons
