Refactor serverless-workflow-builder to redude dependency size

Currently, most dependencies used by serverless workflow are consequence of openapi and rpc-
If a workflow is not using neither of them, there is no way to get rid of them.
Hence, the proposal is to move type handlers for openapi, rpc and asyncapi to different modules.
All these modules will be included in the existing quarkus extension to keep backward compatibility, but when using java executor, user might skip them, reducing considerably the size of dependencies.
