Adds sys:multi_suspend/1,2 and use it in release_handler_1 to send suspend requests in parallel instead of one at a time.

I'm not sure about the new API in sys, but it felt like the cleanest way to do it. Appreciate any takes on it.

Closes #11001

Add sys:multi_suspend/1,2 and use it in release_handler_1 to
send suspend requests in parallel instead of one at a time.
