[build] Remove Java.Interop.TypeNameMappings project, it is gone (#837)

Bumps to Java.Interop/d15-5/53b91e3f.

This fixes JavaNativeTypeManager.PackageNamingPolicy initialization issue
that blocks the entire use of package naming policy customization (one in
Xamarin.Android.Build.Tasks.dll is initialized in GenerateJavaStubs, while
the actual use in Java.Interop.Tools.JavaCallableWrappers.dll never gets
initialized).

Added test for PackageNamingPolicy.Lowercase. Deployed apps work fine too.

The newly added source is positioned at the weird location because
there is a hack around positioning sources:
