Improve Page Editor element control overlay

[Pavel910]

Changes

This PR introduces the following changes:

• Element Control Overlay (ECO) now supports new props: canDrag, canEdit, canHighlight, and canActivate
• there's a new useMoveElement hook, which exposes utilities to move any element up or down within its parent element
• element ErrorBoundary now renders a much more informative output, and logs information about the failed element in the dev tools
• react-composition now resolves the composition scope going through the entire composition scope hierarchy, all the way to the top
• CMS Entry form errors are now correctly passed to the Form component

How Has This Been Tested?

Manually, by adding a plugin for Page Editor with various customizations.
