Rollup merge of #57375 - stjepang:duration-constants, r=joshtriplett
Add duration constants Add constants `SECOND`, `MILLISECOND`, `MICROSECOND`, and `NANOSECOND` to `core::time`. This will make working with durations more ergonomic. Compare: ```rust // Convenient, but deprecated function. thread::sleep_ms(2000); // The current canonical way to sleep for two seconds. thread::sleep(Duration::from_secs(2)); // Sleeping using one of the new constants. thread::sleep(2 * SECOND); ```
