Add png's to Image profile url generation

We currently serve 800px wide profile images inside facia avatar cutouts. This PR enables us to pass cut-outs to our new png resizing service and in turn reducing the foot print of facia pages.

- Add switch for resizing service
- Add profile to Cutout view helper
- Add tests
- Add media service as supported backend to png resizer
