[clang-format] `(*)` is not annotated as `FunctionTypeLParen`

[prj-]

Works OK with version 19.1.0, but with Debian clang-format version 20.0.0 (++20240917111146+1e23a6142a82-1~exp1~20240917111312.2342), I get:

$ clang-format foobar.c
int main() {
  if (type == NON_UNIFORM)
    return (PetscErrorCode(*)(void *, void *, PetscInt,
                              ...))&PCTFS_rvec_non_uniform;
  return 0;
}
$ clang-format-20 foobar.c 
int main() {
  if (type == NON_UNIFORM)
    return (PetscErrorCode(*)(void *, void *, PetscInt, ...)) &
           PCTFS_rvec_non_uniform;
  return 0;
}

It was OK with 20240831100704%2B8aa8c0590c09-1~exp1~20240831220720.2307.

If you tell clang-format that PetscErrorCode is a type name, the left parenthsis in (*) is annotated as FunctionTypeLParen, and the output looks correct.

Note that there should be a space between PetscErrorCode and (.
