These classes were hoisted and renamed. This has been replaced in
Chromium as well. This is a mechanical change for Brave, done with the
following script.
```
git grep -lw 'Value::List' | xargs sed -i 's/\bValue::List\b/ListValue/g'
git grep -lw 'Value::Dict' | xargs sed -i 's/\bValue::Dict\b/DictValue/g'
git cl format
```
