[nativeaot] Log location of the actual p/invoke stub called

Context: 869b0e0

The `pinvoke_unreachable` function, when invoked, would log
its own source location instead of that of the call site.
That's a bit useless in diagnosing issues, so let's improve
it by logging the call site location... :)
