Fix crash of concurrent Win TTS synthesis

[rkusa]

Fixes a crash related to Windows' TTS as reported in Discord. This seems to be caused by a certain concurrency of the synthesis. I don't really know the exact cause (could be Windows - Rust interop), but simply preventing concurrency seems to fix it.

[uriba107]

Just to chime in.
I've ran one of my Hound demo missions with a DLL built from this branch. the fix seems to have done the trick and my mission was able to run correctly (I was a maximum of 14 messages in 2 seconds, usually two or 3 are the same message sent on different channels).

here is a random chunks of debug log
