[clang-format] [C++20] [Modules] Unexpected/Uncontrollable indentation for export block

[ChuanqiXu9]

Reproducer:

export module a;
export {
int aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa(int xxxxxxxxxxxxxxxxxxxxxxx, int xxxxxxxxxxxxxxx);
}

after format we got:

export module a;
export {
  int aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa(
      int xxxxxxxxxxxxxxxxxxxxxxx, int xxxxxxxxxxxxxxx);
}

But we don't want the indentation. Or we hope we can control the behavior by an option like NamespaceIndentation (https://clang.llvm.org/docs/ClangFormatStyleOptions.html#namespaceindentation)

---

Expected output:

export module a;
export {
int aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa(
    int xxxxxxxxxxxxxxxxxxxxxxx, int xxxxxxxxxxxxxxx);
}

What's your expected output?

Sorry. Updated now. The key point is, I don't want the indentation for every declaration in export { block. It is ugly.
