New Frontend Module: React Web Components (non SPA)

Would be nice to have an option to generate the project with a frontend module that follows react web components approach (non SPA)

Two options:
1. Extension of general frontend module so that we can still use existing approach for standard content components + react web components approach for specific, frontend complex components.
2. Only react web components approach

https://github.com/adobe/react-webcomponent
https://github.com/adobe/aem-react-core-wcm-components-examples/tree/master/react-webcomponents-example-project

Start by reviewing the linked adobe/react-webcomponent repository and the react-webcomponents-example-project. Compare the two proposed generation options and determine the expected archetype entry points from those examples; done means the project generator supports the agreed non-SPA React Web Components setup with documented generated output.
