Tree View doesn't support virtualization for long-list items. It will be nice to have this feature.

Summary 💡

To maintain consistency with Autocomplete, it's better to use react-window as a virtualization library. To keep the current API, the Tree View component should merge items to flat list and by using indents present items. (https://material-ui.com/components/lists/#nested-list)

Motivation 🔦

Most of the time tree view uses for long lists and structured data. If the parent item has 1000 children, the performance slows down.
