Add setting to disable formatting

[phoppermann]

The C/C++ extension for Visual Studio Code supports source code formatting using clang-format and vc_format. Both of these formatting options are included in the extension, with clang-format being the default.
[...]
By default, if an .editorconfig file with relevant settings is identified near the code being formatted, the Visual C++ formatting engine is used instead of clang-format.

The clangd extension overwrites this and enforces clang-format. Thus defining the format via .editorconfig is impossible.

Add a setting to disable formatting in the clangd extension and fall back to formatting by the C/C++ extension.

I believe the existing setting "editor.defaultFormatter" should work for this purpose.

I wasn't aware of this setting. Could you add a small hint in https://github.com/clangd/vscode-clangd?tab=readme-ov-file#formatting?

Sure; I sent out #768.
