Rollup merge of #110866 - compiler-errors:test, r=jyn514

Make `method-not-found-generic-arg-elision.rs` error message not path dependent

Every time I bless `tests/ui/methods/method-not-found-generic-arg-elision.rs`, I get some nonsense "type is too long" + "written to disk" that shows up and have to manually revert because the combination of my rustc repo path + the UI test directory hits the length limit for printing types spilling to disk (since this happens before UI test path sanitization).

The fact that we use a closure in this test doesn't have to do with the UI test, so just box the closure to make the type name smaller and not path dependent.
