Message : Vulkan: add clear test for emulated stencil or depth formats S8_UINT and D24_UNORM_X8_UINT are the only formats currently that are single-aspect and are possibly emulated with a packed depth-stencil format if it's not supported. A flag to FeaturesVk has been added as a way to force this behavior for the sake of testing. This test is added to ensure the correct clear algorithm is used for this case. Additionally, this case is detected and the other aspect is forcefully cleared to 0 whenever the original aspect is cleared.
