ci: cross-compile Windows tests and CLI binaries on Linux with cargo-xwin

Windows jobs previously compiled the workspace (test job) and the
release NAPI binding plus vp binaries (cli-e2e-test, 3 cli-snap-test
shards, install-e2e-test-sfw) on slow windows-latest runners, costing
about 24 minutes per job on every NAPI binding cache miss.

Apply the approach from voidzero-dev/vite-task#443:

- build-windows-tests (Linux) cross-compiles workspace tests with
  cargo-xwin into a portable cargo-nextest archive and runs the
  Windows-target cargo check with -D warnings; the run-only
  test-windows job downloads the archive and runs it without a Rust
  toolchain (--test-threads 1 because serial_test in-process locks do
  not span nextest's process-per-test model).
- build-windows-cli (Linux) cross-builds the release binding via
  napi build -x and vp.exe/vp-shim.exe/vp-setup.exe via cargo xwin
  build, published as the windows-cli-binaries artifact; the Windows
  entries of cli-e2e-test, cli-snap-test, and install-e2e-test-sfw
  download it and skip native builds via build-upstream's new
  skip-native input.

Release builds are unaffected and keep building natively on Windows
(reusable-release-build cache keys differ via RELEASE_BUILD/VERSION).
