Subject: [PATCH v2 2/7] scripts: python: Introduce thread sample processing
 to create thread

The _addThreadSample function is responsible for adding a sample to a specific
thread. It first checks if the thread exists in the thread_map dictionary.
If not, it creates a new thread using the _createtread function and assigns
it to the thread_map. Finally, it calls the 'addSample' method of the thread,
passing the thread name, stack, and timestamp.
