refactor(editor): extract widgets (#12304)

<!-- This is an auto-generated comment: release notes by coderabbit.ai -->
## Summary by CodeRabbit

- **New Features**
  - Introduced two new widgets: Edgeless Dragging Area and Note Slicer, now available for use.
  - Added extension support for these widgets, enabling enhanced interaction and integration within the application.

- **Chores**
  - Updated package configurations and workspace settings to include the new widgets and their dependencies.
  - Added project references and configuration files to support modular development and build processes.
