 {{{
 #!CommitTicketReference repository="" revision="37521"
 Database: Obey locale-specific `utf8` collation settings.

 Some sites prefer to use locale-specific location settings. For example,
 the Swedish WordPress package use `utf8_swedish_ci`, instead of
 `utf8_unicode_ci`. When upgrading the connection to `utf8mb4`, we were
 overriding this to be `utf8mb4_unicode_ci`, instead of maintaining the use
 of the `_swedish_ci` variant.

 The locale-specific collations do have extra collation rules just for that
 language, so it's useful to maintain compatibility.

 Fixes #32405.
