Modifications to build C++ with Visual Studio 2026 and the v145 toolset. (#9359)

* Modifications to build C++ with Visual Studio 2026 and the v145 toolset.

* Fixes linker settings for rocksdb for Debug and Release builds

* module is a C++ 20 keyword. Explicitly stating namespace allows cpp20 projects to build against the library

* Fixes crash when initializing an object with the initialize function when some of the attributes are empty, {}, or omitted, std::nullopt

* cleanup for vs2026 v145 toolset per @aothms review

* Fixes bug, IfcCurveSegment.setStartLength was setSegmentLength in alignment_helper.cpp

* Bumps boost to 1.92
