Rollup merge of #110476 - compiler-errors:ty-err-ctxt-good-path, r=lcnr

Browse Source 
Delay a good path bug on drop for `TypeErrCtxt` (instead of a regular delayed bug)

r? `@lcnr`
Perhaps we should just delete the `Drop` impl altogether though?

Fixes rust-lang/rust-clippy#10645

`@matthiaskrgr:` I don't know how to make a clippy test for this. Any idea? Clippy's UI tests run with `-D warnings` and I have no idea how to switch it off to make a test that triggers this ICE in the clippy test suite 🤣
