Summary

If a ParameterExpression has no unbound parameters, the underlying bound value can be hashed instead of the tuple that accounts for the symbolic expression. Doing this allows for the ParameterExpression to match the hash for the numeric value it compares equal to.

Closes #12487

* Use hash of numeric value for bound parameter expressions

If a `ParameterExpression` has no unbound parameters, the underlying
bound value can be hashed instead of the tuple that accounts for the
symbolic expression. Doing this allows for the `ParameterExpression` to
match the hash for the numeric value it compares equal to.

Closes #12487

* Add release note
