Auto merge of #102484 - beetrees:duration-debug-bug-fix, r=scottmcm
Fix integer overflow in `format!("{:.0?}", Duration::MAX)`
Currently `format!("{:.0?}", Duration::MAX)` causes an integer overflow in the `Duration` `Debug` impl ([playground link](https://play.rust-lang.org/?version=nightly&mode=debug&edition=2021&gist=67675c6895bdb2e37ee727f0ed7622b2)). This is because the carry from the rounding of the fractional_part into the integer_part will cause the integer_part to overflow as it is already `u64::MAX`. This PR uses a larger integer type to avoid that issue, and adds a test for the correct behaviour.
