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 where someone looks for this feature on Windows.

Here is a found image of Finder on Mac.
