FUJITA Tomonori e600425708 rust: print: Add support for calling a function exactly once ...

Add the Rust equivalent of the kernel's `DO_ONCE_LITE` macro. While it
would be possible to implement the feature entirely as a Rust macro,
the functionality that can be implemented as regular functions has
been extracted and implemented as the `OnceLite` struct for better
code maintainability.
