a. error: depthAttachment PixelFormat (MTLPixelFormatInvalid) and stencilAttachment PixelFormat (MTLPixelFormat Depth32Float_Stencil8) must match.
b. Because we only support D24S8(D32FS8) combined format, so needs check
TargetBuffferFlags::DEPTH_AND_STENCIL when setup depth and stencil
format, otherwise newRenderPipelineWithDescriptor will crash.
