Ported filament shrinkage compensation for XY and independent Z from Prusa Slicer (fixing MMU painting, seam painting, support painting issues) (#6507)

Browse source 
* Ported filament shrinkage compensation from Prusa Slicer. Updated logic to be 100 = no shrinkage to be consistent with orca definitions

* Code comments update

* Merge branch 'main' into Filament-Shrinkage-compension---port-from-Prusa-slicer

* Merge remote-tracking branch 'upstream/main' into Filament-Shrinkage-compension---port-from-Prusa-slicer

* Merge branch 'main' into Filament-Shrinkage-compension---port-from-Prusa-slicer
