Add API to `Traverse` for cloning an `IdentifierReference` multiple times

See: #5014 (review)

Ideally we should not use TraverseCtx::clone_identifier_reference multiple times for same identifier as it does a lookup of the SymbolId each time. But Dunqing's point that it's very verbose to use TraverseCtx::create_bound_reference_id is reasonable.

Add an API to TraverseCtx to make this short and easy. Something like BoundIdentifier (https://github.com/oxc-project/oxc/blob/main/crates/oxc_transformer/src/helpers/bindings.rs).

#6293 moves BoundIdentifier into oxc_traverse and #6294 makes generate_uid return a BoundIdentifier. Once they're merged, that should close this issue.
