SWF-Editor: Create SWF package for ts/react flow editor

[handreyrc]

The goal of this task is to create a starting point for the development of the new SWF editor based on ts / react / react flow.
A new package shall be created to host the new editor development and it must follow as much as possible DMN editor's code structucture and standards. This way we ensure compatibility with the current tooling architecture and make it easy to new contributors to follow and join the project.

• Create swf-editor package on kie-tools
• It shall be possible to build and run the package (build scripts)
• The code shall be clean and functional
• Zustand shall be set as state manager
• It shall be possible to render a simple workflow of generic nodes (shape and label) and edges from a static model (Marshallers will be tackled later)
