06e602afd3 \#9480 Fix weird path connections in Extra Perimeters when gap fill is applied 
\#9513 \#9489 Fix crash when brim is used - the expansion of very small drops may result in empty polygon, which the support spot generator did not reflect
Fix crashes of stability alert checker, when empty print object was passed to it

ca0c83d914 The new ExtrusionRole implementation newly supports both "Bridging" 
and "External" attributes at the same time.
PerimeterGenerator was updated to make use of it and set "External"
attribute for overhang perimeters.

5991850db1 WIP Extending the expressivity of ExtrusionRole 
Co-authored-by: supermerill <merill@free.fr>
Based on the unfinished idea of @supermerill, defining ExtrusionRole
as a bit mask of ExtrusionRoleModifier.
Because the ExtrusionRole was used for both ExtrusionEntity and
G-code export / G-code viewer, the original ExtrusionRole had to be split
to ExtrusionRole and GCodeExtrusionRole to support bitmask attributes
for the former while keeing a low number of ordinary values for the latter.

f1c0c61895 Refactored Point / MultiPoint / Polyline / Polygon: 
1) Removed virtual methods. There was not really need for them.
2) Some of the virtual methods were using conversion to Lines, which
   was unnecessary and expensive.
3) Removed some nearest element search methods from Point.

d041fa6c0c Refactored PerimeterGenerator to output out_fill_surfaces as ExPolygons, 
not SurfaceCollection.

Reworked combineinfill.t, 07_extrusionpath.t, 08_extrusionloop.t to c++.
Removed Layer / ExtrusionPath / ExtrusionLoop / ExtrusionEntityCollection
from Perl bindings.

237e56c7ce Follow-up to ee626eb65a1a41ec7fd3e00f7b39d048c2795516 
Refactored PerimeterGenerator for functional style, better constness
with the goal of calling PerimeterGenerator::process_xxx()
for each surface at once to collect its fill expolygons.

c9ddf7315e Replaced parameters wall_add_middle_threshold and wall_split_middle_threshold with automatic computation based on extrusion width. 
That allows computed better values in cases when the extrusion width of the first layer or for the infill differs from the extrusion width for perimeters.

Parameters min_feature_size and wall_transition_length now can be set in percentages, and then they will be calculated based on nozzle size. Old profiles with default values are forced to replace old default values with new default values in percentages.

e2e1272003 Fix of #8455 - Fixed the incorrect computation of the threshold for grouping ExtrusionPaths with the same extrusion width in thick_polyline_to_extrusion_paths() that was affecting Arachne and gap fill. 
The previous behavior didn't merge two ExtrusionPaths with the same extrusion width, and it also could merge two ExtrusionPaths with different widths, which was unintentional, and it could also possibly create visible artifacts in some cases.
Because simplification of ExtrusionLoop in GCode::extrude_loop is working on ExtrusionPath and not on whole ExtrusionLoop, so previous incorrect behavior was preventing simplification and removing small extrusions like in #8455.
