What does this PR do?

This PR adds optional Flashpack integration for significantly faster model weight loading.
Read this blog to understand what flashpack is.

  • adds use_flashpack parameter to enable flashpack loading
  • automatic graceful fallback to safetensors if flashpack is unavailable or incompatible
  • supports variant parameter for specific weight files (e.g., model.fp16.flashpack)
  • feature is optional via use_flashpack=True

Fixes # (12550)

Requires optional dependency: pip install flashpack

flashpack repository: https://github.com/fal-ai/flashpack
