test: remove ineffective link-extern-crate-with-drop-type test

Closes #157477

Removed `tests/ui/cross-crate/link-extern-crate-with-drop-type.rs` and its auxiliary file. As discussed in the issue, this test was meant for language-level "resources" which were removed from Rust long ago, making the current test ineffective.

Verified locally that the remaining tests in `tests/ui/cross-crate` pass successfully.
