LOG: [test] Fix aggregate initialization incompatible with c++20

In C++20, types that declare or delete any constructors are no longer aggregates, breaking compilation of many existing uses of aggregate initialization. In this test, provide a one-arg constructor so that `StructWithoutCopyOrMove{1}` still works.
