When promoting scalar arguments to vectors for builtins like `ldexp`, `pown`, and `rootn`, use the correct vector type matching the argument element type instead of always using the return type: these builtins take an integer argument but at the same time have floating point return type Fix `ldexp` test that does not pass spirv-val and add similar tests for `pown` and `rootn` related to https://github.com/llvm/llvm-project/issues/190736
