Add machine_disallowed_areas and turn off nozzle offsetting for disallowed areas calculation

Browse source 
CURA-3663

We don't need to calculate the disallowed areas for certain machines
because they have taken into account the nozzle offsets. This commit
does the following:
- Add machine_disallowed_areas
- Add a flag in definition so that disallowed areas calculation with
  nozzle offsets becomes optional in Cura.

Update documentation for no offsetting for nozzles

Contributes to issue CURA-3663.
