Implemente the `CANCEL ALL` feature

opensource COBOL 4J does not have support for the `CANCEL ALL` feature.
In versions prior to v1.1.0, `CobolResolve.cancelAll` existed and could be used, but its functionality is not sufficient and needs to be updated. In particular, the behavior must be restricted so that it only cancels child programs (i.e., programs below the current one), not everything.
