Feature: Undo duplicate file on first Esc

After pressing the duplicate option, I should be able to undo the file duplication by pressing ESC.

So that you know, the file should not be created or dumped in the recycle bin. As if it was never there.

@trandaison Can you look into this matter?

@backermanbd This could be a breaking changes, since the current duplication behavior is a sequence of copying the file then run the rename command (which is built in command from vscode) on the duplicated file.
The Escape key press event will be treated as cancel renaming. I am not sure if vscode do fire the "cancel renaming" event.

BTW, I will deep dive into it when I have time. Thanks for your feedback.
