 Database: Split the logic of `wpdb::init_charset()` into a separate
 method.

 The logic for determining the appropriate character set and collation to
 use is becoming more complex, particularly with the recent additions of
 [37522] and [37523]. As `init_charset()` has side effects, and makes use
 of constants instead of parameters, it's not possible to unit test this
 logic.

 This commit splits the logic part of `init_charset()` out into a new
 method, `wpdb::determine_charset()`, along with appropriate unit tests.

 See #32105, #37522.

 Fixes #36917.
