Check constant exists instead of rescuing

[ewhorton]

This pull request refactors the logic for creating record classes in lib/rulezilla/dsl.rb to improve code organization and readability. The main change is breaking up the monolithic create_klass method into smaller, single-responsibility methods. This makes the code easier to maintain and understand, while also refining how support modules are included.

Refactoring and code organization:

• Split the create_klass method into three distinct methods: create_record_class, setup_record_class, and define_record_methods, each handling a specific part of the record class creation process.
• Updated the inclusion of support modules to use a safer conditional check (Object.const_defined?) before including, preventing unnecessary exceptions if the module does not exist.

Visibility and method encapsulation:

• Added the new helper methods (create_record_class, setup_record_class, define_record_methods) to the list of private class methods, ensuring proper encapsulation and restricting their access to internal use only.
