refactor: use XCEngine::Math module in sphere test, update matrix to left-handed coordinate system

Browse Source 
- Use Matrix4x4 type directly instead of float[16]
- Remove wrapper functions (IdentityMatrix, TranslationMatrix, PerspectiveMatrix, LookAtMatrix, MultiplyMatrix, TransposeMatrix)
- Direct use of Matrix4x4::Identity(), Matrix4x4::Translation(), Matrix4x4::Perspective()
- Transpose matrices before uploading to GPU to match HLSL column-major
- Update Math module Perspective and Orthographic to left-handed coordinate system
- Update math unit tests for new matrix values
