Changed the storage and application of IParametersValidator instances from a global Set to a Map keyed by object, ensuring validators only see their own object's parameters. This resolves the bug where validators on a @ParametersDelegate saw top-level parameters (e.g., --argtop), making mutex group implementation more intuitive. Updated addDescription and validateOptions accordingly.

This PR fixes issue #575, where an
IParametersValidatoron a@ParametersDelegateobject incorrectly saw all parameters, including those from the top-level object (e.g., --argtop alongside --arg1 and --arg2). The fix scopes validators to their respective object’s parameters, improving intuitiveness and enabling easier mutex group implementation, as noted by@ekpdt.
