Subject: [PATCH 3/9] scripts: python: Introduce thread sample processing in
 convertPerfScriptProfile

The _addThreadSample function is responsible for adding a sample to a specific
thread. It takes the process ID (pid), thread ID (tid), thread name, timestamp
(time_stamp), and stack as parameters. It first checks if the thread exists in
the threadMap dictionary. If not, it creates a new thread using the _createtread
function and assigns it to the threadMap. Finally, it calls the 'addSample' method
of the thread, passing the thread name, stack, and timestamp.
