Description
In the pint integration tests I tried to also test calling numpy functions on xarray objects (we provide methods for all of them).
Some of these functions, like numpy.median, numpy.searchsorted and numpy.clip, depend on __array_function__ (i.e. not __array_ufunc__) to dispatch. However, neither Dataset nor DataArray (nor Variable, I think?) define these protocols (see #3643).
Should we define __array_function__ on xarray objects?

Research direction
Start with the pint integration tests and the discussion in #3643, then inspect how Dataset, DataArray, and Variable currently dispatch NumPy operations. Determine whether array_function should be added and define the supported behavior for functions such as numpy.median, numpy.searchsorted, and numpy.clip; done means the decision is implemented and those integration cases are covered.
