TabHelperDelegateInstaller is a utility class template that sets up
delegates for tab helpers for all the WebStates in a Browser.  Now that
OverlayPresenter can be used to implement tab-specific UI functionality,
tab helpers can show UI without delegating this functionality to
coordinators.  This coupled with the increasing usage of BrowserAgents
in preparation for multi-window support means that more tab helpers will
be using Browser-scoped C++ delegates implemented in BrowserAgents.
