This CL implements a Resource that aggressively reports overuse or underuse until the encoded stream has the max pixels specified. The pixel limit is controlled with a field trial, e.g: --force-fieldtrials="WebRTC-PixelLimitResource/Enabled-307200/" This caps the resolution to 307200 (=640x480). This can be used by the TestBed to simulate being CPU limited. Note that the resource doesn't care about degradation preference at the moment, so if the degradation preference would be set to "maintain-resolution" the PixelLimitResource would never stop reporting overuse and we would quickly get a low-FPS stream. PixelLimitResource runs a repeating task and reports overuse, underuse or neither every 5 seconds. This ensures we quickly reach the desired resolution. Unit tests are added. I did not add any integration tests (I think that's overkill for a testing-only resource) but I have manually verified that this works as intended. This CL also moves the FakeVideoStreamInputStateProvider into a test/ folder and exposes video_stream_adapter.cc's GetLowerResolutionThan().
