refactor(RHI): complete PipelineState Unity SRP style refactoring

Browse Source 
- Fix Chinese character encoding issues causing MSVC C4819 warnings
- Add m_rootSignature member to D3D12PipelineState for PSO creation
- All integration tests pass: OpenGL 4/4, D3D12 4/4
- All RHI unit tests pass: 158/158
