clang-tidy's functionality not works with clangd version 18

System information

Clangd version: 18.1.3 clangd extension version: 0.1.28 Operating system: Windows 11 23H2 or Arch Linux

Reproduction

1. Install clangd

In Arch, install clang-git in archlinux-cn repo.
In Windows, install msys2 first and then in UCRT environment install mingw-w64-ucrt-x86_64-clang-tools-extra. After install add
/ucrt64/bin to PATH
2. Demo

test.cpp:
```
#include <iostream>
```

auto main() -> int { std::cout << "Hello, World!" << std::endl; return 0; }

**.clangd**
```yaml
Diagnostics:
  ClangTidy:
    Add: [performance-*]

Expected

Under std::endl, clang-tidy prompt you: Do not use 'std::endl' with streams; use '\n' instead (fix available)clang-tidy performance-avoid-endl

In fact

Nothing will report. clang-tidy not works.

Workaround

In Arch I can just use clang package with version 17.

In Windows I can install clangd 17 through the automatic installation by clangd extensiton. And then in the clangd config add:

CompileFlags:
  Add: [--target=x86_64-w64-windows-gnu]

But the annoying thing is it will add clangd.path to my vscode settings.json. I sync settings between Arch and Windows. So the path is not the same.

Vscode now does not support scoping settings by platform according to issues 207760. So it is not that convenient.
