Print::validate: added epsilon checks on nozzle and filament diameter validation (https://github.com/prusa3d/PrusaSlicer/issues/2737)

Browse source 
Changed messagebox text after changing extruder diameter with single extruder printers so it is more obvious why it shows

In case nozzle diameters differ and someone checks 'single_extruder_mm', PrusaSlicer asks whether all diameters should be unified. Answering NO did not undo the SEMM check. It does now.
