Revert of Android: Remove VideoCapturer (patchset #2 id:20001 of https://codereview.webrtc.org/1684403002/ )

Reason for revert:
Breaks downstream compilation. Please reland in a non-breaking fashion.

Original issue's description:
> Android: Remove VideoCapturer
>
> This CL makes PeerConnectionFactory.createVideoSource() and nativeCreateVideoSource work directly with VideoCapturerAndroid instead of going via VideoCapturer. The native part is now created in nativeCreateVideoSource() instead of doing it immediately in VideoCapturerAndroid.create().

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.

Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.

The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others. This page is maintained by the Google Chrome team.

Development

See http://www.webrtc.org/native-code/development for instructions on how to get started developing with the native code.
