Add test cases verifying that `CMAKE_APPLE_SILICON_PROCESSOR` set as either a cache or environment variable causes that to be selected as the host architecture. Also verify that sources compile using whatever is selected as the host architecture, even when the explicit setting is not used. Issue: #21554
