sergeyu b4c7b8365d Revert of Use std::unique_ptr<> to pass frame ownership in DesktopCapturer impls. (patchset #7 id:140001 of https://codereview.webrtc.org/1988783003/ )
Reason for revert:
Broke chromium builder

Original issue's description:
> Use std::unique_ptr<> to pass frame ownership in DesktopCapturer impls.
>
> Previously raw pointers were used for owned DesktopFrame instances.
> Updated all screen and window capturer implementations to use
> std::unique_ptr<>.
>
> Also includes some other cleanups in the capturers:
>  - s/NULL/nullptr
>  - moved default initializers to class definition.
