NEW_FILE and NEW_FOLDER in front of navigator toolbar should show with icons like vscode

What it does

close #11425.

Make NEW_FILE and NEW_FOLDER Commands in front of navigator toolbar show at the beginning, instead of manually clicking to expand the menu.

Take NEW_FILE for example. At first I just added iconClass to CommonCommands.NEW_FILE, but it would make show its icon anywhere, such as in filetree right menu and File Menu. So I have forked CommonCommands.NEW_FILE and the previous configuration remains unchanged.

The final behavior:

How to test

1. Hover mouse to projectName of treeview.
2. Click Top Menu File.
3. Right Click some files or folders on File Tree.
4. Have a look with menu show behavior. What needs to be guaranteed most is these two commands in these places can run normally just like before.

Unfortunately the way you duplicated commands is problematic and leads to multiple entries in the command palette:

I'll create a pull-request to resolve the problem.
