Fixes #112226. Similar to #114585, the ETW stackwalk may fail if there is a breakpoint on the stack.

Pull Request Overview

This PR adds ETW nostack entries for DebugExceptionProcessing events to prevent ETW stackwalk failures when breakpoints are present on the stack. This follows the same pattern established in #114585 for similar debug-related events.

Key Changes

  • Adds nostack entries for DebugExceptionProcessingStart and DebugExceptionProcessingEnd events

A little sad to lose this, but as long as the regular exception ones still contain a stack, it's ok.
