Fix Windows link.exe shadowing and cuda-core test group self-reference

- Replace cuda-core[test] with {include-group = "test"} in cuda-core's
  test-cu* dependency groups. The self-reference triggered setuptools_scm
  via the build backend in CI containers without full git context.
- Pass VCToolsInstallDir through CIBW_ENVIRONMENT_PASS_WINDOWS and
  prepend its bin dir to PATH so MSVC's link.exe is found instead of
  Git's /usr/bin/link.exe when DISTUTILS_USE_SDK=1 skips vcvarsall.bat.
- Regenerate uv.lock.
