feat(editor): add bs affine foundation module (#12012)

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

## Summary by CodeRabbit

- **New Features**
  - Introduced the Affine Foundation package, providing a centralized layer for initializing core UI effects, custom elements, and foundational services.
  - Added new foundational store and view extensions to improve core service registration and UI effect setup.

- **Refactor**
  - Streamlined and reorganized block, store, and view extension arrays to rely on the new foundation layer, reducing duplication and simplifying extension management.
  - Removed redundant or now-centralized services and UI effects from existing modules.

- **Chores**
  - Updated configuration files and workspace dependencies to support the new Affine Foundation package.
