localrepo: subclass the new `ilocalrepositoryfilestorage` Protocol class

This is the same transformation as 3a90a6fd710d did for dirstate, but the
CamelCase naming was already cleaned up here.  See 4ef6dbc27a99 for the benefits
of explicit subclassing.

Since there's only one method in this Protocol class and it needs to be
abstract because of the direct subclassing (see cdd4bc69bfc1), do that here.
