Fix review issues and TRX publishing

- Restore XA4313 AndroidError for Xamarin.Android.NUnitLite in Common.targets
- Restore NUnitLite in XA4313 test Values in BuildTest.cs
- Restore GenerateAssemblyInfo=false and AssemblyInfo.cs in TestRunner.Core
- Delete unused MainActivities and Main.axml layout
- Move MyFragment to its own file (still needed by FragmentFixup tests)
- Fix TRX publishing: copy device-pulled TRX to expected path instead
  of relying on --logger trx which doesn't work with Microsoft.Android.Run
