Remove ProfileName from the surface of CoreSettings (#19261)

You know how much I hate squirreling away information on objects we have
to pass halfway across the universe just to get back.

In this case, `StartingTitle` will always be the name of the profile. We
only used ProfileName in places where we _needed a Title_, so this makes
it much more obvious what we're doing.
