cli: add a debug command for generic working copy info
We have two other kinds of working copies at Google and it's sometimes useful to get the basic information about operation id and tree id for them, for exampel for debugging stale workspaces. This patch adds a command for that. We could instead have made the old `jj debug working-copy` command work for all kinds of working copies (like the new command) and only have extra information for the standard local-disk implementation. I don't feel strongly either way and could do it other other way instead if people prefer that.
