feat: add RHI abstraction layer unit tests

- Add RHITestFixture with RHI_BACKEND env var support for backend selection - Add unit tests for: Device, Buffer, Texture, SwapChain, CommandList, CommandQueue, Shader, Fence, Sampler - Tests can run against D3D12 or OpenGL backends via RHI_BACKEND env var - Add integration folder placeholder for future integration tests
