ENH: __pandas_priority__

[jbrockmendel]

Will allow dask/modin to address #38946 and modin-project/modin#4646, respectively.

Also can be used to make non-masked EAs defer to masked EAs.

@jbrockmendel I see there is no feedback from others here. But I guess we'll need documentation if we want to merge this. It should also help the discussion, I checked the referred issues, but it's not immediately clear how the new attribute works.

+1 on this change. I proposed a more detailed version of the documentation, but other than that this looks good, in particular if NumPy is already doing it this way.

@jbrockmendel Would there be a release note needed for this?

[jbrockmendel]

Added a whatsnew, not sure how to make a reference to _extending.pandas_priority

[jbrockmendel]

@jreback suggestions on how to get the whatsnew to point to the appropriate place in the docs?
