    fix(v3.7.x): not merging available_ecu_ids from child ECUs status resp again (#290)

    This PR fixes an unexpected implementation details which prevents the available_ecu_ids for actually behaving as expected.

    This is caused by:
    * ota_client_stub module merges the available_ecu_ids from sub ECU's status response.
    * ecu_info parsing logic has an implicit implementation detail for backward compatibility, which when available_ecu_ids is not defined in the ecu_info.yaml, add this ECU id into this field.

    The above effectively disabling the functionality of available_ecu_ids, unless the corresponding ECU contacts that don't need OTA also being commented out in ecu_info.yaml.

    With this PR, now the available_ecu_ids field should work as expected, and the behavior aligns with the documentation, which only available_ecu_ids from the main ECU is respected.
