Upgrade clipper & improve multi-thread performance (#7177)

Browse Source 
* Clipper: Verify range of int32 coordinates on input.

Cherry-picked from prusa3d/PrusaSlicer@fa7debf49d

Co-authored-by: Vojtech Bubnik <bubnikv@gmail.com>

* ClipperLib: Optimized PointInPolygon() to calculate cross products
 with int64s instead of doubles.

Cherry-picked from prusa3d/PrusaSlicer@9dca8403fe

* Reworked the ClipperLib / Polygon types to use
the tbb::scallable_allocator to better scale on multiple threads.

* use tbb::scallable_allocator for Polygons and ExPolygon::holes
to better scale on multiple threads

* Fixed compilation on GCC and CLang

* ClipperLib: Further optimization of memory allocation using scalable_allocator.
ClipperLib: SimplifyPolygon() - changed default winding number to positive,
      added strictly_simple parameter.
ClipperUtlis simplify_polygons() - removed "remove_collinear" parameter

* ClipperLib: emplace_back() instead of push_back().

* Fixed issue in a 32bit clipper, where IntersectPoint() checked for
the Y coordinate of the calculated intersection point for validity,
but the Y coordinate was already rounded to 32bits, thus an overflow
may have in rare cases masked invalidity of the result.

* Fixed Vojtech's out of boundary assert in Clipper library.
