Review comment:
Since we are cleaning up the code here, how about we make the responsibility
of each rule more clear? What I have in my mind is:
1. `ResolveInsertInto` should only resolve the `InsertIntoStatement`,
instead of the relation itself. Ideally it should only match
`InsertIntoStatement(DataSourceV2Relation, ...)`, and let other rules to
resolve relations.
2. `ResolveTables` should resolve `UnresolvedRelation` inside
`InsertIntoStatement`, similar to the existing `ResolveRelations` rule.
