[NativeAot] Objective-C Marshal: find method handle when propagating exceptions

[AustinWise]

Specifically pass the lastMethod parameter to the UnhandledExceptionPropagationHandler delegate.

At the time this issue was created, the Xamarin side does not use this parameter, so it was not implemented in #80334 . See that PR's comments for some ideas on how to implement it.
