Consider setting clipboard register as the default for yanking/deleting

[joelostblom]

Would you consider setting the system clipboard register as the default for yank/delete operation on supported platforms? We had some discussion of this in jupyterlab-vim here https://github.com/jupyterlab-contrib/jupyterlab-vim/issues/79

Possible concern where a fallback would be needed https://github.com/replit/codemirror-vim/pull/36#issuecomment-1186192936

I believe the request here is an option akin to :set clipboard=unnamedplus, rather than a request to set this as the default (since this isn't the default in vim either)
