Add script to generate macOS icon file. It does not attempt to integrate with the current build process as the macOS icon file is mostly static. `libsvg` was chosen because of its low dependency count over other solutions that use backends like Chromium, PhontomJS, etc. ImageMagick's `convert` was tested but resulting PNGs where not satisfactory and would have required an overcomplicated script having to calculate the `density` argument. * Has a dependency on librsvg (can be installed via Brew) * Uses SVG file as input * Can be integrated in later to build process if desired Closes #7455
