Stabilize the Duration API

This commit stabilizes the `std::time` module and the `Duration` type.
`Duration::span` remains unstable, and the `Display` implementation for
`Duration` has been removed as it is still being reworked and all trait
implementations for stable types are de facto stable.

This is a [breaking-change] to those using `Duration`'s `Display`
implementation.
