Feature: Add TreeView Layout

> [!important]
> Please note, this GitHub issue is keeping track of two separate but related features. A Tree View sidebar, and a Tree View layout. We're currently working on the Tree View Sidebar, please see our latest update for more details https://github.com/files-community/Files/issues/1928#issuecomment-4594354376.

**Is your feature request related to a problem? Please describe.**

Typically, I work in a project folder. That folder might have multiple sub folders like: `images`, `src`, `prints`, `presentations`. With Windows Explorer and Files, I must keep navigating in and out of folders. I want a view of all my files and folders in one view. Much like how VS Code's 'Explorer' handles files display and navigation, or how Mac's Finder handles.

**Describe the solution you'd like**

In list view, I'd like a tree navigation component for files allowing me to expand a folder to list is child files and folders (which can be expanded too)

**Describe alternatives you've considered**
None. I've tried for years now without this feature on Windows. Still miss it sorely from Mac.

**Additional context**
There is [discussion on Reddit](https://www.reddit.com/r/windows/comments/lbygg/osx_finder_style_tree_view_for_windows/) where someone looks for this feature on Windows.

Here is a found image of Finder on Mac.
