fix(build): Decouple WWMath from WWVegas to fix isolated tools CI

Extracted wwmath.h from tight coupling with the 3D engine's always.h
macro definitions to establish WWMath as an independent Level 1 base library
interface. Exposes Libraries/Source/WWVegas/WWMath and gamemath
directly to corei_libraries_include targets, ensuring low-level utilities
like Babylon and versionUpdate can compile BaseType.h without transitive
rendering dependencies.
