[YouTube] Move channel header's verified status code to YoutubeChannelHelper 

This code will be used by YoutubeChannelTabExtractor to return whether
the channel is verified in the corresponding property of all InfoItems from
this channel.

Also throw an exception when we cannot get the verified status of a channel in
YoutubeChannelExtractor due to a missing channelHeader, if the channel has no
channelAgeGateRenderer.
