Code Hinting for Rust is really Slow

## Version

- VS Code CodeQL extension version: 1.17.7
- VS Code version: Version: 1.107.1 (Universal)
- Platform: MacOS

## **Description of the issue**

Currently, I'm writing CodeQL for Rust in VS Code; however, the code hinting is really slow, and the issue does not exist when writing a ql script for GoLang.

Here are some parts of the logs in CodeQL Language Server.
```log

Start by reproducing the slow CodeQL hinting in VS Code with the reported Rust query files, especially solana-queries/src/signer-authorization.ql and rust/elements/internal/AstNodeImpl.qll. Review the CodeQL Language Server logs around textDocument/inlayHint and textDocument/hover, then compare the behavior with Go. Done means the Rust editor requests complete responsively without cancellation or the reported unresolved diagnostics.
