[rct_tools/video_encoder] Add video encoder tool

This CL adds a new video encode tool that supports to encode video at
specified codec, scalability mode, resolution, frame rate, bitrate,
key frame interval and the number of encoding frames.

The video encoder accepts video frames from `FrameGeneratorInterface`,
and supports `SquareFrameGenerator`, `SlideFrameGenerator` and
`IvfFileFrameGenerator`.

All the encoded bitstreams are wrote into ivf output files.

The purposes of this video encoder tool are:
1. Check the functionalities of video codecs and scalability modes.
2. Optimize video quality at different encode setting.
3. Fine tune the bitrate controller.
4. Compare the quality of different codecs at the same setting.
5. And more.

TESTS: Run the tool at 1280x720, 30fps, 2000kbps, 100 GOP, 300 frames:
vp8 [L1T1 L1T3]
h264 [L1T1 L1T3]
vp9 [L1T1 L1T3 L3T3_KEY]
av1 [L1T1 L1T3 L3T3_KEY]
