Win Video Capture: Create an STA |video_capture_thread_| from MediaStreamManager.

YCWebCameraSource.ax causes a huge amount of Chrome crashes. This CL
changes the initialization model of the Device Thread, a.k.a Audio
Thread, from Multiple Thread appartment model to Single Thread model,
MTA -> STA.

We'll monitor the crash rate in the Canaries to see if it has the
desired effect.

Refactoring of DevTools bridge tests: taking advantage of Commands for proxying client-server communication.

Since client and server live on different threads in tests thier communication are proxied. Anounimous classes
are used for that. Since now we have Command's that essentially are call-to-object mapping thay may be used
instead aonymous objects.
