This needs class comments.  Additionally, we only name classes with the *IOS
suffix if they're iOS implementations of interfaces that are shared across
platforms.  Since this class is specific to iOS, I don't think the suffix is
necessary here; maybe just use an abstract interface in components/ then an
implementation with the *Impl suffix would work better.

Optional nit: Per C+++ Style Guide this should be HandleFaviconUrl, however we
don't follow that rule and generally very inconsistent with URL capitalization.
