[KT-32929] Filter exceptions from objc alloc (#3318)

Issue: 
SIGSEGV in Throwable.printStackTrace when terminating after ObjC alloc exception

Root-cause: 
Corrupted kotlin.Throwable has been sent as ReportUnhandledException() parameter

Fix: 
Use @FilterException which terminates correctly with objc_terminate
