Rollup merge of #145135 - Kivooeo:stabilize-duration_constructors_lite, r=ChrisDenton

Stabilize `duration_constructors_lite` feature

This closes [tracking issue](https://github.com/rust-lang/rust/issues/140881) and stabilises `Duration::from_hours` and `Duration::from_mins` while not touching a `duration_constructors` feature from the related [tracking issue (2)](https://github.com/rust-lang/rust/issues/120301)
