MAINT: PR 23269 revisions
* guard masked array `__deepcopy__` special object
handling behind `dtype.hasobject`, based on reviewer
feedback
* masked array `__deepcopy__` for object type handling
now deepcopies from `self._data` directly, based on
reviewer feedback
* add a test case for 2D masked array object
deepcopies, since reviewer was not convinced this was
working
