Pull Request Overview
This PR ports crash dump analysis improvements from main to the .NET 10 Preview 7 branch. The changes serialize unhandled exception information for crash dump analysis when ExceptionHandler.RaiseUnhandledExceptionEvent is called and implement a blocking mechanism to prevent early process exit during serialization.
Key changes:
- Adds crash info serialization for unhandled exceptions in NativeAOT scenarios
- Refactors crash info serialization into a reusable method with thread-safe coordination
- Implements blocking behavior to ensure crash data serialization completes before process termination
