Auto merge of #108118 - oli-obk:lazy_typeck, r=cjgillot

Run various queries from other queries instead of explicitly in phases

These are just legacy leftovers from when rustc didn't have a query system. While there are more cleanups of this sort that can be done here, I want to land them in smaller steps.

This phased order of query invocations was already a lie, as any query that looks at types (e.g. the wf checks run before) can invoke e.g. const eval which invokes borrowck, which invokes typeck, ...
