David Sherret b064c95e93 fix(npm): improve peer dependency resolution with circular dependencies (#18069)
This improves peer dependency resolution yet again. We did not handle
scenarios like the following:

```
// a -> b -> c -> d -> c -> b (peer)
```

...which would maybe work ok the first time its run in some cases, but
then lead to a lockfile that would error on load.

This now keeps track of circular dependencies and updates nodes
accordingly. That said, there is still a lurking bug in this code
somewhere that I've added a comment for (there is a mitigation on the
tail end that seems to work well). The current state is much better than
before and I can look into it later. I think it's something small that's
incorrect.
