WP-Builder: Introduce new NavigatorLayout

[bangank36]

Summary

• The POC PR has provided me with some ideas to implement the Gutenberg Navigator component into jsonforms
• The new Layout will based on the MaterialVertialLayout, where the elements of the layout are rendered using renderLayoutElements method
• For starter, the Navigator will render on 1st level only, in the next phase we will address the question about how we render all NavigatorSreens recursively based on all object/array props

Reference

• Investigation issue can be found here 🖍️ WP-Builder: Integrate Form builder with Gutenberg Navigator #17
• This Pr is also an answer for the question: multi forms or 01 form1, the current approach is render the Navigator inside 01 Form instance
• 🖍️ WP-Builder: Implement renderers #3

The PR has been merged

• The NavigatorLayout should be place at the root of uischema
• All the NavigatorScreen will be render at first, based on the extracted nested object key utils
• Next implement the ObjectRenderer to render only the NavigatorButton, since the detail of the object property has been placed on the NavigatorScreen already
