Add better error message if causal treatment features contain dropped features

[tongyu-microsoft]

This PR adds better error message if causal treatment features contain dropped features:
(responsibleai.exceptions.UserConfigValidationException: '{dropped_feature_name}' in treatment_features has been dropped during training the model)

Description

We added dropped_features where users can choose to drop certain features from the model. In the case when user adds causal component, while treatment features contain dropped features, we need to have a better error message saying "'{dropped_feature_name}' in treatment_features has been dropped during training the model"
