refactor(editor): config the extension provider directly (#12252)

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

## Summary by CodeRabbit

- **New Features**
	- Added new export paths to improve module accessibility for foundation store and view components.
	- Introduced new extension points for telemetry, font configuration, link preview cache, and peek view services in the view extension foundation.

- **Improvements**
	- Enhanced flexibility by allowing optional configuration of placeholders in paragraph view extensions.
	- Switched to runtime schema validation for font configuration, increasing reliability.
	- Streamlined service registration for peek view providers.

- **Refactor**
	- Centralized and simplified extension management by removing redundant extension files and consolidating setup logic.
	- Updated internal integration of telemetry, font, and peek view services for improved maintainability.
