Visit Identifier node as part of the SourceOrderVisitor (#17110)

Browse source 
## Summary

I don't remember exactly when we made `Identifier` a node but it is now
considered a node (it implements `AnyNodeRef`, it has a range). However,
we never updated
the `SourceOrderVisitor` to visit identifiers because we never had a use
case for it and visiting new nodes can change how the formatter
associates comments (breaking change!).
This PR updates the `SourceOrderVisitor` to visit identifiers and
changes the formatter comment visitor to skip identifiers (updating the
visitor might be desired because it could help simplifying some comment
placement logic but this is out of scope for this PR).
