bug(windows): (silent) crash on exit of kmshell relating to CEFShutdown

Looking at a recent crash dump for [KEYMAN-WINDOWS-12Y](https://keyman.sentry.io/issues/3144201342/), it looks like there is still a race condition, and it is not clear what the cause is. The crash is not terribly harmful as it appears to be silent and happens on shutdown of kmshell.exe, but would be good to fix all the same.
