Add support of texture frames for video capturer.
This is a reland of r6252. The video_capture_tests failure on
builder Android Chromium-APK Tests should be flaky.
- Add ViECapturer unittest.
- Add CloneFrame function in I420VideoFrame.
- Encoders do not support texture yet and texture frames
are dropped in ViEEncoder for now.
