Refactor: Composable disentangling (#5695)

## Summary

Prerequisite refactor/cleanup to use a global store instead of having
nodes throw up events to a parent component that stores a reference to a
singleton service that itself bootstraps and synchronizes with a
separate service to maintain a partially reactive but not fully reactive
set of states that describe some but not all aspects of the nodes on
either the litegraph, the vue side, or both.

## Changes

- **What**: Refactoring, the behavior should not change.
- **Dependencies**: A type utility to help with Vue component props

## Review Focus

Is there something about the current structure that this could affect
that would not be caught by our tests or using the application?
