Backport of #29555.
Fixes #29344.
It seems that for datetime dtypes,
arraydescr_reducewas initializing a new mapping instead of setting toPy_None, and thenarraydescr_setstatejust read it in. I set the metadata to and then checked forPy_Noneand refactored some of the logic to be clearer hopefully.Adding a test. Thanks for reviewing!
