Revert "use tcx.used_crates(()) more" before it reaches beta

[lqd]

There are more open issues caused by #124976 than will be fixed by #125493 alone. The beta cut is soon, so let's revert it and buy some time to analyze and fix these issues in our own time.

Nice that you added tests!

[lqd]

Only one, though I should probably add the last mcve, that seems doable as an rmake test since ui tests won’t work. The other issues can involve hundreds of crates so there are no repros unfortunately.

edit: it's not yet possible to add the #125474 mcve as an rmake test.
