refactor(traverse, semantic): move rename_symbol from TraverseScoping to Scoping (#10611)

Part of https://github.com/oxc-project/backlog/issues/163

Prepare #10612. I just found that this method has a `to_string`
allocation that can be avoided. However, it needs to combine
`set_symbol_name` and `rename_binding`, so move to `Semantic`.
