Add shutdown tasks functionality to application

Browse Source 
A new method OnShutdown was introduced to allow adding tasks to be run when the application shuts down. The shutdown tasks are run on the main thread and in the order they were added, with the application option `OnShutdown` being run first. This allows more controlled and managed shutdown of the application.
