 {{{
 #!CommitTicketReference repository="" revision="33055"
 Enable utf8mb4 for MySQL extension users. Previously utf8mb4 was limited
 to MySQLi users only unintentionally.
 This change does the following things
  * Allows utf8mb4 for the MySQL extension
  * Re-runs the utf8->utf8mb4 conversion for single sites, this will do
 nothing for tables already converted
  * Re-runs the utf8->utf8mb4 conversion for global tables in multisite
 when the environment supports utf8mb4
  * Removes upgrade_420() calling as upgrade_430() will perform those
 changes now instead

 The index shortenings should have still taken place on utf8 sites
 previously, so there's no need to run those again.

 Props kovshenin, pento, dd32
 Fixes #32127 for trunk.
