Generate PowerShell wrappers for emcc & co. #18213
Description
When trying to interrupt test runner on Windows, I'm getting a very verbose output from various parallel processes, e.g.:
Test suites:
['test_core']
Running test_core: (5 tests)
Using 5 parallel test processes

KeyboardInterrupt
Aside from that, for some weird reason when I run tests and interrupt them in VSCode Terminal instead of ConEmu or standard Windows thing, the VSCode terminal often becomes completely unuseable and behaves as if all my input keys are still piped elsewhere (into the test runner process?) so I can't execute any other commands on the command line w/o restarting the terminal.
I realise this is not a particularly helpful explanation or amount of details, but I'm not sure what else to add w/o someone also trying this out on Windows.
