Replace the examples in the documentation by the ones from the user-space version and introduce the standalone examples from the user-space version such as the `CMutex<T>` type. The `CMutex<T>` example from the pinned-init repository [1] is used in several documentation examples in the user-space version instead of the kernel `Mutex<T>` type (as it's not available). In order to split off the pin-init crate, all examples need to be free of kernel-specific types.
