Add support for controlling output of OpenAPI Generator version in generated files (#17952)

* add initial openapi config and java generated files * add java implementation for adding generator version * regenerate sample client files * remove tabs * only show generated version if build info exists * set build info for batch generation * update generator doc for new global flag * use existing property for generator version * update templates to include generator version * update templates for better generator version syntax * revert undesired changes * regenerate samples for openapi client * update templates to correct formatting/newlines * correct description text and add to usage doc * add generator cli option for all codegen types * use more concise version info; update existing codegens to support new prop * correct wrong prop reference * add initial test coverage for new prop * update last (scala) templates with new prop * update samples after upstream merge * use consistent version output * use better sample project id/name * revert using option for generator version in templates
