enabled enhanced bookmarks flag for all users

Enabled enhanced bookmarks flag for all users.
Enhanced bookmarks flag option was used to be shown only if user enrolled into experiment. Enabling it for all users because if user has multiple profiles there is no currently a way to enable this option properly.
Long term fix would be to make about_flags aware of user preferences.
For now showing to all users looks like a "lesser evil" then not giving an option to opt-out of experiment.

Am I reading this correctly? Doesn't this mean that it's permanently in
about:flags and anybody can opt-in?

From my understanding, the server would still need to send down a CRX
identifier, either via sync or finch, to actually do anything.  There may be
complications outside of the desktop experience.

lgtm but please wait for Eric to approve

I think this is fine from both Desktop/Android sides but not sure if there's any
impact on iOS. AFAIK, the new model code won't magically start doing anything
based on this flag unless we're showing the new UI.
