Delete Concrete(Read|Data)AttributePath equality operator (#32131)

* Delete Concrete(Read|Data)AttributePath equality operator

Right now these default to using the ConcreteAttributePath equality
operator, which is misleading because it will return true for objects
which are not actually equal.

Replace this with the MatchesConcreteAttributePath
function.

A new equality operator for these classes will be introduced in a
follow-up PR. I'm introducing this change separately to ensure that CI
catches any current usage of the equality operator.
