66344aca9c Update video codec tester unit tests
* Add VideoCodecTesterTest and move Run[EncodeDecode]Test() into it. The class will be extended with functionality necessary for testing simulcast/SVC (it will collect and store decode input frame sizes in particular) in follow-up CLs, which will add simulcast/SVC support to the tester.
* Add TestVideoEncoder and TestVideoDecoder classes.
* Use frame size instead of timestamp in checks in Slice test. Unlike timestamp, which has the same value for spatial layer frames within a temporal unit, frame size is a unique frame property in these tests.

d431156c0e Move codecs handling from test to tester
* Pass codec factories to the video codec tester instead of creating and wrapping codecs into a tester-specific wrappers in video_codec_test.cc. The motivation for this change is to simplify the tests by moving complexity to the tester.

* Merge codec stats and analysis into the tester and move the tester. The merge fixes circular deps issues. Modularization is not strictly needed for testing framework like the video codec tester. It is still possible to unit test underlaying modules with rather small overhead.

* Move the video codec tester from api/ to test/. test/ is accessible from outside of WebRTC which enables reusing the tester in downstream projects.

Test output ~matches before and after this refactoring. There is a small difference that is caused by changes in qpMax: 63 -> 56 (kDefaultVideoMaxQpVpx). 56 is what WebRTC uses by default for VPx/AV1 encoders.
