Stuart Cook 1d49de5b06 Rollup merge of #153376 - Zoxc:cycle-waiters-iter, r=nnethercote ...

Replace `visit_waiters` with `abstracted_waiters_of`

This replaces `visit_waiters` which uses closures to visit waiters with `abstracted_waiters_of` which returns a list of waiters. This makes the control flow of their users a bit clearer.

Additionally `abstracted_waiters_of` includes non-query waiters unlike `visit_waiters`. This means that `connected_to_root` now considers resumable waiters from the compiler root as being connected to root, while previously only non-resumable waiters counted. This can result in some additional entry points being found. Similarly in the loop detecting entry points we now consider queries in the cycle with direct resumable waiters from the compiler root as being entry points.

When looking for entry points we now look at waiters until we found a query to populate the `EntryPoint.waiter` field instead of stopping when we determined it to be an entry point.
