powertop-macos: init at 1.3.3

Add the macOS PowerTop menu bar application under a macOS-qualified name to avoid colliding with the existing Linux powertop package.

Upstream is source-available and ships build.sh, but the source build currently requires newer Apple Swift Observation macro support than nixpkgs' Swift 5.10 provides. Package the upstream release zip instead and mark the package as binaryNativeCode.
