Putting these classes in a sub folder increases structure and clarifies that they are used as helper classes. Affected classes in this change: * CodecTimer * InterFrameDelay * RttFilter VCMTiming will be moved in a separate CL. Additional changes: * Remove VCM prefix from class names. * Introduce granular BUILD.gn targets. * Update some includes.
