feat: Add GoogleSlidesTools toolkit (Closes #6829)

[anshul-jain-devx108]

Summary

Adds a new GoogleSlidesTools toolkit that enables Agno agents to create, read, and manage Google Slides presentations via the Google Slides API.

This completes Google Workspace coverage in Agno — Sheets, Docs, Drive, Calendar, Gmail all have toolkits, but Slides was missing.

The toolkit provides 19 tools covering presentation management, slide operations, content creation, content reading, and advanced batch updates. Authentication follows the same pattern as GoogleSheetsTools (OAuth, env vars, service account).

Issue: #6829
