Rollup merge of #97494 - est31:remove_box_alloc_tests, r=Dylan-DPC

Use Box::new() instead of box syntax in library tests

The tests inside `library/*` have no reason to use `box` syntax as they have 0 performance relevance. Therefore, we can safely remove them (instead of having to use alternatives like the one in #97293).
