Build out the `form-js-render` package

[Skaiir]

Is your feature request related to a problem? Please describe.

As part of the current refactoring project to separate the form-viewer into a renderer and core part. This issue tracks the renderer side.

Describe the solution you'd like

We should have a project that takes a single form representation object and renders it out. We should also provide an easy playground-like interface to test this project with manually.

Additional context

Root issue: #1166

[marcosgvieira]

@Skaiir as agreed, let's break the milestones here so it's easier to understand when we target to deliver.

[Skaiir]

On this one, there isn't so much a milestone approach, as there are many small things to tackle. What matters with this part of the issue is that it is done by the time #1208 is done.
