Description
Is your feature request related to a problem? Please describe.
Currently ds.nbytes returns the size of the data.
But sys.getsizeof(ds) returns a very small number.
Describe the solution you'd like
If we implement __sizeof__ on DataArrays & Datasets, this would work.
I think that would be something like ds.nbytes + the size of the ds container, + maybe attrs if those aren't handled by .nbytes?

Research direction
Start with the DataArray and Dataset objects, their existing nbytes behavior, and Python's sys.getsizeof/sizeof entry points. Define whether the result includes the data, container, and attrs, then confirm the agreed sizing semantics for both object types.
