[SPARK-36435][PYTHON] Implement MultIndex.equal_levels

[itholic]

What changes were proposed in this pull request?

This PR proposes implementing MultiIndex.equal_levels.

>>> psmidx1 = ps.MultiIndex.from_tuples([("a", "x"), ("b", "y"), ("c", "z")])
>>> psmidx2 = ps.MultiIndex.from_tuples([("b", "y"), ("a", "x"), ("c", "z")])
>>> psmidx1.equal_levels(psmidx2)
True

>>> psmidx1 = ps.MultiIndex.from_tuples([("a", "x"), ("b", "y"), ("c", "z"), ("a", "y")])
>>> psmidx2 = ps.MultiIndex.from_tuples([("a", "y"), ("b", "x"), ("c", "z"), ("c", "x")])
>>> psmidx1.equal_levels(psmidx2)
True

This was originally proposed in databricks/koalas#1789, and all reviews in origin PR has been resolved.

Why are the changes needed?

We should support the pandas API as much as possible for pandas-on-Spark module.

Does this PR introduce any user-facing change?

Yes, the MultiIndex.equal_levels API is available.
