Better drag and drop / clipboard integration of files across applications

[bpasero]

This includes being able to drag files and folders from VS Code into other applications as well as to being able to copy a file or folder to the native clipboard.

Specifically:

• copy files/folders from VS Code file explorer to clipboard and paste into native OS explorer
• copy files/folders from native OS explorer and paste into VS Code file explorer (Explorer: allow to paste files from the clipboard into target folder #130036)
• support the native file data transfer when doing drag and drop (Support for native file transfer / clipboard support electron/electron#2853)
• support 3rd party tools such as WinRAR to open files from an archive ([BUG] Can't open unzip file #90196)
• drop files to the desktop to copy them there (Dragging File Tab Out Of VSC No Longer Creates Copy Of File #128975)

Does this cover dragging a folder from desktop to VSCode, and adding that folder into an existing project?

Right now, dragging a folder to an open project/window. Opens a new window on Mac. Which is not what people expect I suppose. Though, dragging a folder to the VSCode app icon should open a new window.

We are explicitly disabling to drop a folder into the explorer to copy it to prevent accidentally large folder-copy operations. We could however allow to drop a folder and ask the user for feedback, so I would say that is independent from this particular issue here.

Played around a little bit with electron/electron#6333 but unfortunately once I do that, no in-app DND seems to be working anymore...
