feat(editor): root block extension (#12063)

Closes: BS-3202

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

- **New Features**
  - Introduced new root block store and view extensions, enhancing modularity and integration options for root block functionality.
  - Exported the EdgelessLocker class for broader usage.

- **Improvements**
  - Updated export paths for root block modules, enabling clearer and more flexible module access.
  - Enhanced view extension setup to better tailor user interface and interactions based on context.

- **Removals**
  - Removed legacy migrating store and view extension logic, streamlining extension management and reducing unused code.
  - Removed multiple deprecated block specifications and common extension collections to simplify the codebase.
  - Deleted AI page root block specification, retaining only lifecycle watcher functionality.

- **Chores**
  - Updated dependencies and project references to support new extension loader integration.
