Tracking Issue for `Duration` saturating operations

[marmeladema]

This is a tracking issue for Duration saturating operations.
The feature gate for the issue is #![feature(duration_saturating_ops)].

        impl Duration {
            pub const fn saturating_add(self, rhs: Duration) -> Duration {}
            pub const fn saturating_sub(self, rhs: Duration) -> Duration {}
            pub const fn saturating_mul(self, rhs: u32) -> Duration {}
        }

Steps

• Implement the proposal: Add saturating methods for Duration #76114
• FCP
• Stabilization PR: Stabilize feature duration_saturating_ops #84090

Unresolved Questions

• Do we want associated constants similar to the ones that already exist for integer types or associated methods? (ie: Duration::MIN or Duration::min()?
• Should Duration::MIN be replaced by Duration::zero()? They are currently equivalent but one can image a future where Duration is able to hold negative duration and thus making MIN different from zero().

Just needed saturating_sub when dealing with time intervals.

Also, unresloved questions seem to be from another tracking issue?
