The Find control in tree view is very useful and highly requested by the community, but still a lot of people are not aware that we already have it in vscode. For the moment, to find something in tree view, you have to

• select an item to focus on the tree view
• press ctrl/cmd + F

To expose the feature more, can we add an option to show a button on view/title as below?

The behavior will look like below.

(I mimic the behavior by calling commands viewId.focus and list.find in above demo...but to add the buttons for multiple views, I have to do that repeatedly registering multiple commands).

As this is a generic feature for all tree views, I think it probably we can add a new option showFindControl in TreeViewOptions, just like how we add "showCollapseAll" button. WDYT?
