MDEV-28769 Assertion `(m_ci->state & 32) || m_with_collate' failed in... 

MDEV-28769 Assertion `(m_ci->state & 32) || m_with_collate' failed in Lex_exact_charset_opt_extended_collate::Lex_exact_charset_opt_extended_collate on SET NAMES

These system variables:
  @@character_set_client
  @@character_set_connection
  @@character_set_database
  @@character_set_filesystem
  @@character_set_results
  @@character_set_server

can now be set in numeric format only to IDs of default collations, e.g.:

SET @@character_set_xxx=9;  -- OK    (latin2_general_ci  is default)
SET @@character_set_xxx=2;  -- ERROR (latin2_czech_cs is not default)
SET @@character_set_xxx=21; -- ERROR (latin2_hungarian_ci is not default)

Before this change the server accepted IDs of non-default collations
so all three examples above worked without errors,
but this could lead to unexpected behavior in later statements.
