AppDomain.AssemblyResolve can be fired/not fired depending on the type of exception thrown by other extension points

[elinor-fung]

If an event handler for AssemblyLoadContext.Resolving or override of AssemblyLoadContext.Load throws a FileNotFoundException, the AppDomain.AssemblyResolve event is still fired, so other extension points still have an opportunity to resolve the assembly.

For any other kind of exception, it is not fired.
