mono_set_pending_exception is a private mono symbol, which means we won't find
it when using the system mono (as a dynamic library). In that case, we'd
abort.
Instead try to call mono_raise_exception, and hope for the best. It will leak
somewhat, but that's still better than asserting.
This changes the generated wrapper function from:
```c
MONO_API void
mono_set_pending_exception (MonoException * exc)
{
if (mono_set_pending_exception_func == NULL)
xamarin_assertion_message ("Could not load mono_set_pending_exception\n");
return mono_set_pending_exception_func (exc);
}
```
to
```c
MONO_API void
mono_set_pending_exception (MonoException * exc)
{
if (mono_set_pending_exception_func == NULL)
return mono_raise_exception (exc);
return mono_set_pending_exception_func (exc);
}
```
Also this only applies to Xamarin.Mac apps that use the system mono (such as VSfM).

The two functions mono_class_is_nullable and mono_class_get_nullable_param are
private mono symbols, which means we can't call them when using Xamarin.Mac
with libmono from a dynamic library.
Implement a fallback for this case, where we call a managed method when these
functions are not available (and restrict this workaround to Xamarin.Mac only,
since it's not needed for Xamarin.iOS).
* [runtime] Use printf on watchOS, NSLog doesn't shown up (by default).
* [runtime] Use a wrapper function for logging.
So that we can chose between printf and NSLog at runtime,
depending on where we're running.
