Delete Concrete(Read|Data)AttributePath equality operator (project-ch…

…ip#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. * Restyled by clang-format * Add unit tests * Restyled by clang-format --------- Co-authored-by: Restyled.io <[email protected]>
