Update time zone data files to tzdata release 2024b.

Historical corrections for Mexico, Mongolia, and Portugal.
Notably, Asia/Choibalsan is now an alias for Asia/Ulaanbaatar
rather than being a separate zone, mainly because the differences
between those zones were found to be based on untrustworthy data.
