This cl move VideoEncoderConfig from api/ to video/config. VideoStreamEncoderInterface and VideoStreamEncoderObserver are moved as collateral. brandt@ think that the reason these were in api/ in the first place had to downstream project. Functionality wise, this is a NOP, but it makes it easier to modify the encoder (config).
