Dawei Wei 610dbfac5e Enable Windows support for BuildKit integration tests ...

This PR adds comprehensive Windows container support to BuildKit's integration test suite,
enabling cross-platform testing while maintaining full Linux compatibility.

- Updated 35+ integration tests to work on both Windows and Linux
- Uses integration.UnixOrWindows() pattern for platform-specific logic
- Windows: nanoserver images, cmd.exe commands, C:\ paths, CRLF handling
- Linux: preserves existing alpine/busybox images and bash/sh commands
- Added platform-specific adaptations for cache, export, frontend, and CLI tests

- Files: 12 modified (+454/-151 lines)
- Coverage: Major test categories now cross-platform compatible
- Compatibility: 100% backward compatible, no breaking changes
- CI: Enables Windows testing in BuildKit pipeline

- Cache import/export (local, registry, multiple backends)
- Image exporters (containerd, OCI, tar, metadata)
- Dockerfile frontend parsing and builds
- buildctl CLI functionality
- Multi-stage builds and named contexts

Tests requiring POSIX features (uid/gid, tmpfs, file modes) remain Linux-only.
