Refactor of screen-builder-renderer

[caleeli]

This refactor must make sure all the current features of screens should work:

• Render all the components
• Render all the containers
• Reactivity of data
• Calculated properties
• Watchers
• Multi-Columns
• Dynamic CSS
• Visibility rules
• Nested screens
• Validations
• page navigation
• Loop Control
• Record List
• Image control

Improvements:

• An organized way to register extensions
• A better way to register new components
• Fix circular calculated fields
• Fix circular watchers
• Improve rendering and execution speed
• Add (unit, vue or E2E) tests to make sure everything is working as expected
