fix: D3D12 CreateTexture defaults and CommandList RTV support

Browse Source 
- Add default value handling for sampleCount, mipLevels, depth in CreateTexture
- Add RTV descriptor heap to D3D12CommandList for future ClearRenderTarget implementation
- ClearRenderTarget remains stub (requires full D3D12 render pipeline state)
