This lets us start taking advantage of featurs from Go 1.23, particularly tracking aliases in go/types and iterators. Note that we need to add code to properly handle or skip over the new *types.Alias type which go/types produces for Go type aliases. Also note that we actually turn this mode off entirely for now, due to the bug reported at https://go.dev/issue/70394. We don't yet remove our own alias tracking code yet due to the above. We hope to be able to remove it very soon.
