Support windows subsystem for linux (WSL) Remote Development

[agreedSkiing]

Feature Description:

The feature to remote into windows subsystem for linux has existed for vscode for quite some time through the ms-vscode-remote.remote-wsl plugin. See also Developing in WSL. The plan is to move the installed application backend to a remote system and connect to a server running on that system.

Agree with above, this would be a killer feature and would allow many more to ditch vscode and aim for using theia instead.

Anyone interested in implementing this can use #13372 and #12618 as a template on how to implement this. In fact, #12618 already provides most of the infrastructure required to make this work.
