Decouple http node from workflows (#13272)

- Added a generic HTTP request tool, allowing agents and workflows to
make HTTP requests to external APIs with configurable method, headers,
and body.
- Decoupled HTTP request workflow nodes from workflow-specific types and
factories, introducing a generic tool interface.
- Updated agent system prompts to include explicit guidance for the HTTP
request tool, including when and how to use it, and how to communicate
limitations.
