...and use the borrowing variant for the NAPI `pathRuleNodes` function to not double-allocate. The borrowing variant is more general in the Rust API; not all use cases want or should rely on previously collecting the path into a Vec of owned `Rc`s.
In preparation to remove the CST `Visitor` trait altogether.

Previously, the TestNodeBuilder would not construct the whitespace children tokens and the printer logic would recognize this as an childless node, whereas the new printer does not, as we only skipped the leading/trailing trivia nodes before.
This should probably be fixed to also not include the EndOfFileTrivia much like the Leading/Trailing variants, however this is not as important as we will change the trivia model soon (DSL v2).

We discussed internally that the Visitor API for (dynamically typed) CST is a lot less useful now that we have the
Iteratorinterface implemented in Rust (and hopefullyIteratorprotocol in TS in the future), so let's remove the CST Visitor API altogether.The Visitor pattern will be a lot useful once we have typed, heterogenous data such as the new AST (#634), so let's wait until then with designing and exposing such interface.
