refactor(component): Convert Tavily Search to standard component pattern

[raphaelchristi]

This pull request modifies the Tavily Search component to follow the standard component pattern used in components like URL fetcher. The main changes are:

• Converts from LCToolComponent to Component to support direct data and text outputs
• Removes tool-specific code and schemas
• Adds text output capabilities alongside data output
• Simplifies error handling to return Data objects instead of raising exceptions
• Renames methods to follow component naming conventions

Key changes:

1. Changed base class from LCToolComponent to Component
2. Added text output capability through fetch_content_text method
3. Modified Data objects to include required text field for message formatting
4. Simplified error handling to match component pattern
5. Removed TavilySearchSchema and build_tool functionality

This change makes the component more consistent with other similar components in the codebase while maintaining the same core search functionality.

@Cristhianzl this will probably break front end tests
