Change validation for the new controller dialog window

[bohdan-harniuk]

TODO:

1. We need to remove old validation from the dialogue (com.magento.idea.magento2plugin.actions.generation.dialog.validator.NewControllerValidator).
2. We need to add all validation rules from removed validator through annotations.

Related Issue & PR as an example:

• Issue: Change validation for the new ViewModel dialog window #302

• PR: Added new validation for new ViewModel dialog #307

The dialogue window we should change with new validation:
com.magento.idea.magento2plugin.actions.generation.dialog.NewControllerDialog

Expected result (*)

1. Added new controller dialogue validation with annotations and it works as before (all previous validation rules are present)
2. Old validation removed from the code
