2.7.0 Update - CPU only

[JamesRobertsonGames]

Pytorch 2.7

Destination channel: defaults

Notice

• osx-arm build and test pipeline is flaky as usual - it will pass on retry
• windows builds timeout on PBP - manual graph submission passes with test skips

Explanation of changes:

• CPU Build only
• MKL 2025 Compatibility assured
• Regenerate patches
• Add patched to fix CUDA build requirement on non-cuda build
• Remove tests which trip up due to CI/CD issues
