Function rust_libretro::retro_cheat_set

#[no_mangle]
pub unsafe extern "C" fn retro_cheat_set(
    index: c_uint, 
    enabled: bool, 
    code: *const c_char
)

Called by the frontend whenever a cheat should be applied.

The format is core-specific but this function lacks a return value, so a Core can’t tell the frontend if it failed to parse a code.
