feat: Error handling and multi-file support in File Component

[erichare]

This Pull Request adds better error handling and a more robust interface for managing file uploads, including support for zip files.

WIP Changes:

• ZIP Archive Support - Added the ability to process multiple text files within a zip archive. If a zip archive is provided, files within are automatically extracted and supported files are processed sequentially or optionally in parallel.
• PDF File Support - Uses the PyMuPDF library to parse text from PDFs.
• Parallel Processing Support - For zip files, process in parallel, optionally.
• Detailed Logging for Processing Stages - Introduced comprehensive logging throughout the file loading and processing stages.
• Graceful Error Handling with Silent Mode - Re-use of Langflow silent_errors option that allows non-blocking error handling, letting users bypass errors on files within a multi-file workflow without error.
• Modularized Processing Logic - Split single and zip file processing into distinct methods, for better readability and maintainability.
