Add "destroy on shutdown" option for synchronous execution

[Marcono1234]

Currently only asyncDestroyOnShutdown exists for async execution. However, no equivalent option exists for synchronous execution. Could you please add such an option?

Synchronous execution can be quite convenient because you see for example the console output of the JavaFX application on the console of Maven, but the problem is currently that if you terminate Maven, the JavaFX application continues to run. This is where such a "destroy on shutdown" could be useful (assuming it works properly when pressing Ctrl + C to stop Maven, or by closing the terminal).
