rust: time: Add HrTimerExpires trait
Introduce the `HrTimerExpires` trait to represent types that can be
used as expiration values for high-resolution timers. Define a
required method, `into_nanos()`, which returns the expiration time as a
raw nanosecond value suitable for use with C's hrtimer APIs.
Also extend the `HrTimerMode` to use the `HrTimerExpires` trait.
This refactoring is a preparation for enabling hrtimer code to work
uniformly with both absolute and relative expiration modes.
