Add unit tests for pandas-inherited pd.MultiIndex methods with ArkoudaExtensionArray #5195
Description
This ticket is the MultiIndex analogue: write unit tests covering pd.MultiIndex methods that are inherited/available via pandas when one or more levels are backed by ArkoudaExtensionArray (or when MultiIndex is constructed from Arkouda-backed arrays).
The goal is to confirm pandas semantics (level/name handling, dtype/NA behavior, indexing/slicing, setops, sorting) and catch regressions in inheritance/dispatch specific to MultiIndex (e.g., level operations, get_level_values, droplevel, reindexing/join behavior).
