Meaning of BaseDtypeTests.test_array_type_with_arg

[TomAugspurger]

#22666 removed that test as (I think) it wasn't functioning properly. The method doesn't take any parameters, so running it would always raise a TypeError. Subclasses had to override it, which ends up just duplicating test_array_type.

cc @jreback, if you recall the motivation for it.

Yep, agree this was duplicating test_array_type now. I think in an original implementation construct_array_type actually had an argument, so this is probably a left over.

(@jreback closing as I think it is rather clear now I look at it, but of course feel free to re-open if you disagree)
