[MDEV-30824] Fix binlog to use 'String' for setting 'character_set_client'bb-10.9-bar-MDEV-30824

Commit a923d6f49c1ad6fd3f4d6ec02e444c26e4d1dfa8 disabled numeric setting
of character_set_* variables with non-default values:

  MariaDB [(none)]> set character_set_client=224;
  ERROR 1115 (42000): Unknown character set: '224'

However the corresponding binlog functionality still write numeric
values for log event, and this will break binlog replay if the value is
not default. Now make the server use 'String' type for
'character_set_client' when generating binlog events

Before:

  /*!\C utf8mb4 *//*!*/;
  SET @@session.character_set_client=224,@@session.collation_connection=224,@@session.collation_server=33/*!*/;

After:

  /*!\C utf8mb4 *//*!*/;
  SET @@session.character_set_client=utf8mb4,@@session.collation_connection=33,@@session.collation_server=8/*!*/;

Note: prior to the previous commit, setting with '224' or '45' or
'utf8mb4' have the same effect, as they all set the parameter to
'utf8mb4'.
