Windows x64 Build Support with xnnpack

[vortex-captain]

Summary

This PR introduces support for out-of-the-box builds on Windows x64 with xnnpack, simplifying the setup process for developers using executorch on Windows. Additionally, it lays the groundwork for future Windows build pipelines and prebuilt PyPI packages.

Fixes #4661
