- The previous logic would run them after finally's, but this change makes them happen when we detect the unhandled exception during first pass EH. Fixes the baseservices/exceptions/UnhandledExceptionHandler/NoEffectInMainThread test

Pull request overview
This PR fixes the timing of UnhandledException handlers in the CoreCLR interpreter to trigger during the first pass exception handling rather than after finally blocks execute. This resolves a test failure in the baseservices/exceptions/UnhandledExceptionHandler/NoEffectInMainThread test.
Key Changes
- Introduces a flag to track when an InterpreterFrame represents a native transition boundary
- Uses this flag to correctly skip the InterpreterFrame when checking for unhandled exceptions
- Ensures unhandled exception detection happens at the correct point in the exception handling flow
