Adds hasRequired to all Java schema classes @wing328
This is needed if one is generating classes for object schemas and one only wants to generate the class if required exists. One could almost do this with #requiredVars but that doesn't work because using #requiredVars mean we move into the context of iterating over each var when we just need to know if there are required vars.
hasRequired is tested in the below models:
- CodegenModel
- CodegenProperty
- CodegenParameter
- CodegenResponse
These tests show that hasRequired (and requiredVars) sometime loose the schema required information as shown in https://github.com/OpenAPITools/openapi-generator/issues/8906
This PR came out of work in https://github.com/OpenAPITools/openapi-generator/pull/8928
