feat: implement D3D12 device initialization with debug layer

D3D12 Core:
- Implement complete device initialization flow
- Add debug layer enablement in DEBUG mode
- Add GPU adapter enumeration and selection
- Add feature level checking (min 11.0)
- Add DXCall and NAME_D3D12_OBJECT macros
- Add release template function
- Configure info queue for error/warning breakpoints

Documentation:
- Add changelog for D3D12 device initialization
- Update D3D12 Wiki with current implementation status
- Add Doxygen comments to Renderer and platform interface
