Add Prusa MK4S profiles (#8279)

* Whitespace cleanup in Prusa profile

```
$ diff -u Prusa.json <(jq --indent 4 < Prusa.json) | wc -l
       0
```

* Add Prusa MK4S profiles

There were generated from the PrusaSlicer profiles[0] using some scripts
which try to faithfully convert the profiles[1]. The high flow nozzle
settings have been modeled as a separate printer model.

A few things I'm aware of that haven't been converted:

 - Filament multi-material settings (eg loading speeds)
 - High-flow and abrasive nozzle check in gcode, which, as far as I
   know, isn't available in the current firmware anyways

I've also found that disabling z-hop on layer change in OrcaSlicer seems
more similar to the behavior in PrusaSlicer (which allows travel
distance limitations to override that setting), so I've disabled that.

Fixes #7391
