Don't start WASAPI render thread until setup completes.
Creating the render thread before setting up the |audio_client_|
may lead to race conditions when repeatedly starting and stopping
a stream.
With this patch, nothing touches |audio_client_| until IAudioClient
triggers the render event for data.
As a bonus, it fixes a destruction issue where |audio_clock| was
being destructed on the wrong thread (render vs audio), see docs:
