* Fix inheritance in DataTree.copy()

Fixes pydata#9454

Previously, we were copying parent coordinates/dimensions onto all
child nodes. This is not obvious in the current repr, but you can see
it from looking at the private `._node_coord_variables` and
`._node_dims`.

To make the use of `_to_dataset_view()` little more obvious, I've added
a required boolean `inherited` argument.

* typing error

* add missing inherited argument

* Apply suggestions from code review
