[Fet] support copy from remote to remote/local machine

[Mon-ius]

current vscode support local -> remote, and remote -> remote if they are same machine, however, it not support from remote to local and remote to remote if they are not same machine, it last for many years, hope such feature can be added, so that we can save a lot of time to manual download the file from remote, open it then copy the content to local.
