Enable Microsoft.AI.MachineLearning NuGet with WinUI projects (#16415)

Microsoft.AI.MachineLearning NuGet fails to build on WinUI projects due
to the conflict between the ReferenceCopy of binaries that occurs with
managed applications, with the manual binplacement that occurs with
native appliactions.

With WinUI, both cases are triggered, and a duplicate binplace is
detected as an error.

Fix: Don't rely on the ReferenceCopy for WinUI applications, and
manually binplace the Microsoft.AI.MachineLearning dll.
