CI: generalize build jobs to multiple platforms

- Add matrix strategy to build, build_wasm, build-tests, and
  build-tests-webrtc jobs
- Support ubuntu-22.04, ubuntu-24.04, ubuntu-24.04-arm, and macos-latest
- Add platform-specific dependency installation (apt vs brew)
- Update artifact names to include OS identifier to avoid conflicts

This enables testing builds across multiple platforms while maintaining
the same functionality.
