Add WinAppSDK SceneGraph CompositionSamples into WinAppSDK directly (#335)
* Port WindowsCompositionSamples into WinAppSDK Moving Microsoft/WindowsCompositionSamples into WindowsAppSDK-Samples * Remove differentiating Platform SDKs The WinAppSDK Scene Graph runs consistently down-level to RS5 (1809) / Server 2019. It does not need to differentiate platform versions. * Fix arm64 build Fix VS config for arm64.
