feat(ci): add Windows ARM64 packaging

[NihilDigit]

Summary

Add Windows ARM64 packaging support to the existing PR and release workflows.

This depends on the Windows ARM64 libmpv support added in Predidit/media-kit#34, and updates Kazumi's media-kit pin to the merged upstream commit.

Changes

• Split the existing Windows build job into windows-amd64 naming.
• Add a Windows ARM64 PR build job on windows-11-arm.
• Add Windows ARM64 release packaging for zip and MSIX.
• Publish Windows artifacts with explicit architecture suffixes:
  • Kazumi_windows_<version>_amd64.zip
  • Kazumi_windows_<version>_arm64.zip
  • Kazumi_windows_<version>_amd64.msix
  • Kazumi_windows_<version>_arm64.msix
• Update media-kit dependencies to Predidit/media-kit@11d02cb804b8faf944137834a1b0ac80880a4079.

Notes

The Windows ARM64 job sets up Flutter by cloning the pubspec-pinned Flutter SDK directly. subosito/flutter-action resolves SDK archives by runner architecture, while the pinned Windows Flutter release currently only publishes an x64 archive. This also avoids depending on jq / yq availability on windows-11-arm.

The release workflow reuses the existing SignPath configuration for Windows zip and MSIX signing. No new secrets are introduced.

Validation

• Ran flutter pub get with the updated media-kit pin.
• Checked the workflow diff against the existing Windows and Linux packaging jobs.

Code Review Summary

Status: No Issues Found | Recommendation: Merge

The ARM64 build/release jobs faithfully mirror the existing amd64 jobs, artifact names are unique per architecture, the workflow-level env: block supplies the required secrets to all jobs, and the Flutter-version regex resolves correctly from environment.flutter in pubspec.yaml. The media-kit pin bump is applied consistently across pubspec.yaml and pubspec.lock.

Note (out of review scope — verify at runtime): dart run msix:create --architecture arm64 is assumed to support the --architecture flag (msix ^3.16.12) and to emit kazumi.msix under build/windows/arm64/runner/Release. This depends on third-party tool behavior that can't be statically verified.

此pr完全破坏了升级功能的兼容性，因为原来的 x86 发布被重命名

我倾向于只升级 media-kit 而不实际发布，但是需要的用户可以在主分支进行编译

之前的 linux arm 也是这样，并且维持了很久
