New parameter "Slicing Mode" for supporting 3DLabPrint airplane models.

Browse source 
S3D's strategy for merging self intersecting models is "Even / Odd"
which PrusaSlicer now supports as an alternative to "Positive" rule.
Also added a "Close Holes" option to fill in all internal structures.
3D-Labprint Models aren't sliceable (till years) #3062 #3708
