Use the extruder count in the global stack in project loading

Browse source 
CURA-4167

Custom FDM printers have multiple extruder stacks by default but not all
of them may be used. The actual number of extruders depends on what's
defined in the global stack. Because in the current architecture,
single-extrusion machines don't have extruder stacks, in project
loading, the extruder count in the global stack should be used so these
cases can be handled properly.
