Initialize COM using the multithreaded apartment

I honestly have no idea which is the correct (or better) mode to use given the
confusing mess COM is, but CoInitialize uses single-threaded apartments which
seems to be a problem for with at least a couple games in the STALKER series
(the call fails, which causes us to drop back to the DSound backend).
