Keep generic suggestion for macro-expanded missing-type items

Fixes rust-lang#157659

If a macro expands to a few missing-type items on the same span (think a `$()*` repeat of `const A = ...;`), they all land on the same stashed `ItemNoType` diagnostic. Only one item gets to steal it and stamp in its own inferred type, and under the parallel front-end which one wins is basically a coin flip. So the suggested type flips between runs: the original repro kept bouncing between `usize` and `bool`.

There isn't really a "right" type to show here anyway, imo. The items can infer different types, so there's no single one to suggest. When the placeholder span comes from a macro I now skip the inferred-type suggestion and keep the parser's generic `<type>` one instead. The fallback arm a few lines down already does the same thing, so it lines up.

Output is deterministic now, so `in-macro` no longer needs `ignore-parallel-frontend`. Checked it by hashing the stderr over a couple hundred `-Z threads=8` runs (all identical) and the touched ui dirs still pass.
