Share native binaries via GitHub artifacts (#92758)
## What
Use the GHA cache instead of turborepo cache for intemediate build
products.
## Why
turborepo is fast, but GHA is pretty fast too (adds a few seconds), and
this takes load off the cache server. As a bonus, we get intermediate
artifacts available for download and we work regardless of cache server
availability.
## Details
- Add `nativeArtifact`/`uploadNativeArtifact` inputs to
`build_reusable.yml`
- Build jobs upload `.node` files as GitHub artifacts
- Test jobs download pre-built artifacts instead of rebuilding via
turborepo cache
- Rust installation and sccache are skipped when downloading pre-built
artifacts
- Both Linux (`next-swc-linux`) and Windows (`next-swc-windows`) native
builds upload artifacts
