Update GitHub Actions dependencies to v4

upload-artifact and download-artifact v3 are deprecated and failing.
v4 no longer allows multiple uploads to the same artifact name, so each
matrix job now uploads to a unique name (native-addon-<os>) and the
download steps use merge-multiple to recombine them.

Also bumps checkout, setup-node, and cache to v4 across all workflows.
