Rename visit_preorder to visit_source_order (#17046)

## Summary

We renamed the `PreorderVisitor` to `SourceOrderVisitor` a long time ago
but it seems that we missed to rename the `visit_preorder` functions to
`visit_source_order`.
This PR renames `visit_preorder` to `visit_source_order`

## Test Plan

`cargo test`
