Austin Orion 0548d18510 Add DesktopCaptureOptions to allow WGC capturer.
This changes add two new options to the DesktopCaptureOptions class so
consumers can opt in to using the WGC capturer. The capturer is still
behind the RTC_ENABLE_WIN_WGC build flag which is off by default, so
these options will have no affect until that flag is enabled.
