Adds boundary/outline/sharp/crease/flush classification of HLR
projection edges in SvgSerializer, so CSS can style silhouettes,
ridges, and valleys differently instead of drawing every edge
identically (fixes the "ugly faceted sphere" problem from #3668).
Classification happens pre-HLR on the original solid's real face
topology (three prior attempts tried to classify HLR's own output,
which carries no face topology at all and can't be correlated back
by edge identity). Each class's visible portion is then extracted via
HLRBRep_HLRToShape::VCompound(S)/OutLineVCompound(S), the same
per-shape filtering mechanism already used for per-product
segmentation, applied per class instead. Classes are tagged directly
on individual <path> elements so Bonsai's merge_linework_and_add_metadata
group-level class rewrite in operator.py never touches them.
New settings: svg-ridge-angle-min-degrees, svg-valley-angle-min-degrees,
svg-emit-flush-edges (ConversionSettings.h), wired through Bonsai's
CreateDrawing operator and exposed via its redo panel.

Property sets contained in an IfcPropertySetDefinitionSet were exported as
an empty element in XML. The XmlSerializer already had a block to expand
such a set into its member property sets, but it was gated behind
#ifdef SCHEMAS_HAS_IfcPropertySetDefinitionSet while the schema generator
emits SCHEMA_HAS_IfcPropertySetDefinitionSet (singular). The plural spelling
is defined nowhere, so the block was dead code and a RelatingPropertyDefinition
holding a set produced nothing.
Correct the macro name so the set is expanded and its property sets are
serialized. The parse layer already reads these nested sets (they are
reachable from util.element), so this only completes the XML path.

roughnessFactor was computed as 1/specularity. An IfcSpecularExponent of
0 produced infinity, which nlohmann::json serialises as null and makes
the glTF invalid; exponents below 1 produced values above 1, which glTF
also forbids. Map exponents <= 1 to full roughness and keep 1/exponent
above that, so the factor always lands in [0, 1].

Fixes builds with newer GCC/libstdc++ that no longer provide <cstdint>,
<cstring>, <cfloat>, <memory>, <algorithm> etc. transitively. Also
disambiguates visit<> calls in taxonomy.h with the full namespace and
casts the character value in IfcCharacterDecoder to uint32_t to silence
ambiguous overload warnings.
