Add a block for C clients in the compatibility header. This block contains only the `@cdecl` functions that are printed using only C types. This C block is printed above the Objective-C and C++ blocks as if we add support for `@cdecl` types other languages should be able to reference them in function signatures. Other languages block don't duplicate printing the `@cdecl` functions either as they are already accessible to them.
