Ref: #57351

Splitting data into chunks is a common operation. Previously, users were relying on np.split which no longer works in pandas 3.0. It seems to me this is a common enough operation that it should have a method in the pandas API.

Proposal: Add Series.split and DataFrame.split with the same signature as np.split (except no axis argument for Series). It should have the same behavior as np.split except that it produces the corresponding pandas objects.
