[libc++][chrono] Fixes format output of negative values. (#89408)
When trying to express a time before the epoch (e.g. "one nanosecond
before 00:01:40 on 1900-01-01")
the date would be shown as:

  1900-01-01 00:01:39.-00000001

After this patch, that time would be correctly shown as:

  1900-01-01 00:01:39.999999999
2024-04-23 19:42:00 +02:00

[libc++][chrono] Fixes (sys|local)_time formatters. (#76456)
- The sys_time formatter is constrained, which was not implemented.
- There is a sys_days formatter which was not implemented.
- The local_time formatter uses the sys_time formatter in its
implementation so "inherited" the same issues.
