LazyLoad: Add support for restricting LazyLoad to Data Saver users.

This CL adds support for restricting the lazy loading of frames and
images separately by field trial parameters. For lazy image loading, to
avoid the performance hit from repeatedly locking the mutex in
NetworkStateNotifier, the value of
NetworkStateNotifier::SaveDataEnabled() is queried once for each frame
and used for all images in that frame.
