rust: hrtimer: add hrtimer::ScopedHrTimerPointer
Add the trait `ScopedHrTimerPointer` to allow safe use of stack allocated
timers. Safety is achieved by pinning the stack in place while timers are
running.
Implement the trait for all types that implement `UnsafeHrTimerPointer`.

rust: hrtimer: introduce hrtimer support
Add support for intrusive use of the hrtimer system. For now,
only add support for embedding one timer per Rust struct.
The hrtimer Rust API is based on the intrusive style pattern introduced by
the Rust workqueue API.
