This change moves ScopedComInitializer out of core_audio_utility and
into rtc_base/win so it can be reused elsewhere more easily.
It also adds HSTRING and GetActivationFactory functionality to
rtc_base/win. These two were heavily based on what is already present
base/win.
All of these are necessary for the new window capturer based on the
Windows.Graphics.Capture API. You can see how these APIs will be
used in this CL: 186603: Implement WgcCaptureSession |
