Rollup merge of #126740 - ferrocene:ja-ui-test-needs-unwind, r=lcnr

add `needs-unwind` to UI test

the `tail-expr-lock-poisoning` UI test uses the `panic::catch_unwind` API so it relies on unwinding being implemented. this test ought not to run on targets that do not support unwinding. add the `needs-unwind` attribute to signal this
