[5.2.x] Fixed #36173 -- Stabilized identity of Concat with an explicit output_field.

When Expression.__init__() overrides make use of *args, **kwargs
captures their argument values are respectively bound as a tuple and
dict instances. These composite values might themselves contain values
that require special identity treatments such as Concat(output_field)
as it's a Field instance.

Refs #30628 which introduced bound Field differentiation but lacked
argument captures handling.

Thanks erchenstein for the report.
