Identity Service: Rename IdentityManager to IdentityManagerImpl

A forthcoming CL is going to introduce a client-side C++ encapsulation
of identity::mojom::IdentityManager. We have decided that the best
name for this client-side C++ class is IdentityManager (following a
pattern set by e.g. interface_provider.h and interface_provider.mojom).
To enable this introduction, we must rename the current
identity::IdentityManager. This CL hence renames this class to
identity::IdentityManagerImpl.

Note that this renaming triggers a bunch of presubmit warnings about
usage of base::Bind() and base::Closure. As this CL is not intended
to be a behavioral change, we simply change these usages to what they
are aliased to: base::BindRepeating() and base::RepeatingClosure.
Future work can convert any of these that are suitable to the
Once variants.
