[clang] [clang-format][NFC] Clean up AnnotatingParser::consumeToken() (PR #142104)

It looks like this change is not actually NFC. The difference is incredibly minor. Given this C++ snippet:

```c++
namespace f {
/*//comment*/};
```

clang-format used to not touch that. Now, it adds a space near the end:

```c++
namespace f {
/*//comment*/ };
```

Is that expected?
