[refactor] Remove TLShapeDef, getShapeUtilByType. (#1432)

This PR removes `TLShapeDef` and associated helpers / references.

It purposely loosens the configuration and typings to better support
customization.

### Change Type

- [x] `major` — Breaking Change

### Test Plan

1. Use the app!

### Release Notes

- [tlschema] Update props of `createTLSchema`
- [editor] Update props of `TldrawEditorConfig`
- [editor] Remove `App.getShapeUtilByType`
- [editor] Update `App.getShapeUtil` to take a type rather than a shape
