chore: fix two comment typos (#22524)

## Summary

-
`datafusion/physical-plan/src/aggregates/group_values/multi_group_by/mod.rs:737`
- `scalarized_intern_remaining` doc said "preform" → "perform"
- `datafusion/core/tests/dataframe/mod.rs:843,895,943` - three
nearly-identical test comments said "functionally dependant" →
"functionally dependent"

Comment-only.
