Mark de Wever 6f2d8cc061 [libc++][chrono] Loads leap-seconds.list in tzdb. (#82113 )

This implements the loading of the leap-seconds.list file and store its
contents in the tzdb struct.

This adds the required `leap_seconds` member.

The class leap_seconds is fully implemented including its non-member
functions.

Implements parts of:
- P0355 Extending <chrono> to Calendars and Time Zones
- P1614 The Mothership has Landed

Implements:
- P1981 Rename leap to leap_second
- LWG3359 <chrono> leap second support should allow for negative leap
seconds
- LWG3383 §[time.zone.leap.nonmembers] sys_seconds should be replaced
with seconds
