- Do not visit implicit AST node the relevant traversal mode.
- Add traversal extension points for concept requirements.
- Renamed `TraverseConceptReference` to mark as helper to share the code. Having an extension point there seems confusing given that there are many concept refences in the AST that do not call the helper. Those are `AutoType`, `AutoTypeLoc` and constraint requirements.

Only clangd code requires an update.

There is really no use-case for concept requirements traversals yet, but
I added them in the earlier version of the patch and decided to keep
them for completeness.
