Subject: [PATCH] Provide a secondary sort order for `wp_get_archives()` when
 `type=postbypost`.

Sorting by post_date alone can cause indeterminacy problems on different
versions of MySQL when post_date ties need to be broken. Using `ID` as a
secondary sort ensures that the order is always determinate.

Props herbmillerjr for an initial patch.
Fixes #30480.
