API Review: ProcessId for ProcessFailedEventArgs

[prija-microsoft]

Add ProcessId property to CoreWebView2ProcessFailedEventArgs4

This API extends ProcessFailedEventArgs to include the process ID of the failed process, enabling applications to:

• Correlate process failures with running process data from the ProcessInfo API
• Collect process-specific diagnostic information for logging and telemetry
• Analyze crash dumps for specific processes
• Better track and respond to failures in multi-renderer scenarios

The process ID is only available if the process has started and ended unexpectedly. For other failure types, the process ID value will be 0.
