Port `update imports on file rename/move` support

[mjbvz]

Similar to #2227, update imports on file rename/move is one of those features that I really miss. Also can't easily be replaced by models right now

Just tried tsgo's ls today and ran into this as well. It's unbelievably faster on our codebase though! Tempted to stick with it for now and just swap ls when I need to do a bunch of file renaming.
