workers: handling exceptions in windows workers
This adds handling of exceptions from worker threads and resurfaces them as if the function ran without workers.
If any of the threads throws, the main thread kills all running threads giving them 5 sec to handle the interruption and raises the first exception received.
We don't have to join threads if is_alive() is false
Test Plan:
Ran multiple updates/enable/disable sparse profile and things worked well
Ran test on CentOS- all tests passing on @ passed here
Added a forged exception into the worker code and got it properly resurfaced and the rest of workers killed: P58642088
