This PR adds comprehensive support for GitHub's new windows-2025 runners across the MSQuic CI/CD pipeline, enabling builds and tests to run on the latest Windows environment.

Overview

GitHub recently introduced windows-2025 runner images, and this change updates our workflows to utilize these new runners while maintaining backward compatibility with existing windows-2022 runners.

Changes Made

Build Workflows:

  • Updated build.yml to include windows-2025 in the build matrix alongside windows-2022 for both regular and official builds
  • Enhanced stress.yml with windows-2025 configurations for stress testing builds and execution
  • Added dotnet-test.yml support for .NET interop testing on windows-2025

Supporting Workflows:

  • Updated plugin builds (plugins.yml) for both WinDbg extensions and QuicTrace
  • Migrated performance testing workflows (wan-perf.yml, netperf.yml) to windows-2025
  • Updated validation workflows (check-clog.yml, check-dotnet.yml)
  • Enhanced Rust/Cargo builds (cargo.yml) to use windows-2025

Technical Approach

The implementation adds windows-2025 as additional matrix options rather than replacing windows-2022, ensuring:

  • Zero breaking changes - existing workflows continue to work
  • Gradual migration - teams can choose which runner to use
  • Comprehensive coverage - both builds and tests supported

Exceptions

Some workflows intentionally remain on windows-2022:

  • Kernel builds - windows-2025 doesn't currently support kernel driver development
  • NuGet packaging - maintains consistent artifact naming
  • Code coverage - preserves analysis consistency

Validation

All modified YAML workflow files have been validated for syntax correctness, and the changes maintain full backward compatibility while extending support to the new runner environment.

Fixes #5242.

Do not change occurences of "windows-latest". Only add "windows-2025" when "windows-2022" is used and windows-2019 was used before support was removed.
