Describe the feature

Vim and Neovim have built-in functionality for indenting C-style programs:

It would be awesome to be able to use this as a formatter like any other in Conform.

Provide background

All of the common C formatters have too many configuration options. As someone who only dabbles with C on occasion, Vim's built-in C-indenting is more than enough for my needs. But I'd love to have it trigger on save rather than running it manually (eg, visually selecting the whole file then hitting =). And having it set up as a formatter in Conform would mean not needing to duplicate format-on-save logic. It would also be great to use the formatter's condition property to check for a .clang-format file and fall back to clangd if it finds one.

What is the significance of this feature?

nice to have
