Eagerly persist on WM_ENDSESSION (#18912)

Browse Source 
Once an application has returned from handling `WM_ENDSESSION`
the OS may kill the app at any point. This means we must
persist our state while inside the message handler.

Closes #17179

Honestly, none. It's a race condition in the first place.
