Add necessary cflags and cflags_cc for winrt compilation. Add 'dawn_is_winuwp'. Set 'dawn_enable_vulkan' and 'dawn_supports_glfw_for_windowing' when compiling for UWP. Link d3d12, d3d11 and dxgi stub libs when compiling for UWP. Use LoadPackagedLibrary instead of LoadLibraryA in DynamicLib when compiling for UWP. Swapchain related changes will be in another commit.
