Tree component (new)

[d13]

Create a set of components that provides a comparable list-style experience commonly generated by VS Code's Tree view API.

Building a tree-view-style UI should be a highly composable dev-experience, supported by a number of components including:

• vscode-tree
• vscode-tree-item
• vscode-toolbar
• vscode-action

Trees should support:

• user preferences: indentation, view-modes (auto, tree, list)
• parent-child node relationships (expanding/collapsing, etc)
• checking off items
• events based on clicking the whole item
• show toolbars when clicked, hovered, or focused
• decorators at the farthest end of the row used to convey status of the item
• if not virtualizing these items, we can probably just use content-visibility
