feat(editor): rich text package (#10689)

This PR performs a significant architectural refactoring by extracting rich text functionality into a dedicated package. Here are the key changes:

1. **New Package Creation**
- Created a new package `@blocksuite/affine-rich-text` to house rich text related functionality
- Moved rich text components, utilities, and types from `@blocksuite/affine-components` to this new package

2. **Dependency Updates**
- Updated multiple block packages to include the new `@blocksuite/affine-rich-text` as a direct dependency:
  - block-callout
  - block-code
  - block-database
  - block-edgeless-text
  - block-embed
  - block-list
  - block-note
  - block-paragraph

3. **Import Path Updates**
- Refactored all imports that previously referenced rich text functionality from `@blocksuite/affine-components/rich-text` to now use `@blocksuite/affine-rich-text`
- Updated imports for components like:
  - DefaultInlineManagerExtension
  - RichText types and interfaces
  - Text manipulation utilities (focusTextModel, textKeymap, etc.)
  - Reference node components and providers

4. **Build Configuration Updates**
- Added references to the new rich text package in the `tsconfig.json` files of all affected packages
- Maintained workspace dependencies using the `workspace:*` version specifier

The primary motivation appears to be:
1. Better separation of concerns by isolating rich text functionality
2. Improved maintainability through more modular package structure
3. Clearer dependencies between packages
4. Potential for better tree-shaking and bundle optimization

This is primarily an architectural improvement that should make the codebase more maintainable and better organized.
