rust: pin-init: change examples to the user-space version

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.
