[Testing] Run Controls.DeviceTests with CoreCLR on Android

[simonrozsival]

Once we have the GC bridge for CoreCLR on Android ready (dotnet/runtime#116310 and dotnet/android#10198), we should run ControlsDeviceTests on Android also with CoreCLR. This will be a very valuable stress test for the experimental support of CoreCLR on Android.

To switch from Mono to CoreCLR, it should only be necessary to add the <UseMonoRuntime>false</UseMonoRuntime> MSBuild property.
