Allow providers to consume AirflowConfigException from compat sdk

[amoghrajesh]

Tests on main are broken similar to:

________________________________________________________________ test_dag_state_change_process_pool_size_invalid_value_raise_error[false] ________________________________________________________________
task-sdk/src/airflow/sdk/_shared/configuration/parser.py:1050: in getint
    return int(val)
E   ValueError: invalid literal for int() with base 10: 'false'

During handling of the above exception, another exception occurred:
providers/openlineage/tests/unit/openlineage/test_conf.py:554: in test_dag_state_change_process_pool_size_invalid_value_raise_error
    dag_state_change_process_pool_size()
providers/openlineage/src/airflow/providers/openlineage/conf.py:155: in dag_state_change_process_pool_size
    return conf.getint(_CONFIG_SECTION, "dag_state_change_process_pool_size", fallback="1")
task-sdk/src/airflow/sdk/_shared/configuration/parser.py:1052: in getint
    raise AirflowConfigException(
E   airflow.sdk._shared.configuration.exceptions.AirflowConfigException: Failed to convert value to int. Please check "dag_state_change_process_pool_size" key in "openlineage" section. Current value: "false".

This is because of #60026. This PR moved conf to compat sdk but not AirflowConfigException, so there was a mismatch in the exception raised and captured. Expected: airflow.exceptions.AirflowConfigException, caught: airflow.sdk._shared.configuration.exceptions.AirflowConfigException.

Hence, moving this exception into compat sdk as well. It would be beneficial in long run to do this.
