### What changes were proposed in this pull request? Fix `Series`/`Index.copy()` to drop extra columns. ### Why are the changes needed? Currently `Series`/`Index.copy()` keeps the copy of the anchor DataFrame which holds unnecessary columns. We can drop those when `Series`/`Index.copy()`. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? Existing tests. Closes #33549 from ueshin/issues/SPARK-36320/index_ops_copy.
