Subject: Change CommonFields from a private base class of raw_hash_set to be
 the first member of the settings_ CompressedTuple so that we can move
 growth_left into CommonFields.

This allows for removing growth_left as a separate argument for a few functions.

Also, move the infoz() accessor functions to be before the data members of CommonFields to comply with the style guide.
