Rollup merge of rust-lang#125927 - ferrocene:lw-alloc-unwind-test, r=pietroalbini
Ignore `vec_deque_alloc_error::test_shrink_to_unwind` test on non-unwind targets rust-lang#123803 added this test which requires unwinding to succeed. This conditionally ignores the test on non-unwind targets (as is the case with other tests using `catch_unwind`).
