Rollup merge of #142825 - jdonszelmann:track-caller, r=oli-obk

Port `#[track_caller]` to the new attribute system

r? ``@oli-obk``

depends on https://github.com/rust-lang/rust/pull/142493

Closes rust-lang/rust#142783

(didn't add a test for this, this situation should simply never come up again, the code was simply wrong. lmk if I should add it, but it won't test something very useful)
