Subject: Add dart lsp config and queries (#1250)

* Add language: dart

The setup requires that dart be in the users path, such as:
```
export PATH="$HOME/Android/flutter/bin/cache/dart-sdk/bin/:$PATH"
```

Refactor the dart highlights

* lang: dart: add indents and locals

* lang: dart: corrections to local scope
