[clang-format] [PR52595] clang-format does not recognize rvalue references to array

https://bugs.llvm.org/show_bug.cgi?id=52595

missing space between `T(&&)` but not between `T (&` due to && being incorrectly thought of as `UnaryOperator`  rather than `PointerOrReference`

```
int operator()(T (&)[N]) { return 0; }
int operator()(T(&&)[N]) { return 1; }
```

Existing Unit tests are changed because actually I think they are originally incorrect, and are inconsistent with the (&) cases that are 4 or 5 lines above them.
