Jonathan Brouwer 2c0daa2301 Rollup merge of #147499 - josh-kaplan:master, r=Mark-Simulacrum ...

Implement round-ties-to-even for Duration Debug for consistency with f64

## Summary

This PR proposes a fix for rust-lang/rust#103747 implementing IEEE-754 S4.3 roundTiesToEven for Duration Debug implementation.

## Testing

Added new test in `time.rs` for  validating roundTiesToEven behavior in Duration formatting. Reran all debug formatting tests in `time.rs` with `./x test library/coretests --test-args time::debug_formatting`.
