feat: add win32-ia32 and darwin-arm64 (macOS Apple Silicon) npm packages (#108)

Add two new platform targets to the datadog-serverless-compat CI pipeline:

- win32-ia32: 32-bit Windows build via native windows-2022 runner
  (i686-pc-windows-msvc, UPX-compressed)
- darwin-arm64: macOS Apple Silicon build via native macos-14 runner
  (aarch64-apple-darwin, no UPX — preserves Mach-O code signing)

Each platform adds a build step to build-datadog-serverless-compat.yml,
artifact download/processing in the package job, and an npm publish line
in the publish job of publish.yml.
