Backporting patch for Bug#47756

Browse Source 
from mysql-next-mr-bugfixing into mysql-trunk-bugfixing.

NOTE: the "utf8_phone_ci" collation does not exist in mysql-trunk yet,
so another collation with 2-byte collation ID is used: "utf8_test_ci".

This patch will be null-merged to mysql-next-mr-bugfixing.

message:
  Bug#47756 Setting 2byte collation ID with 'set names' crashes the server
  
  The problem is not actually related to 2byte collation IDs.
  The same crash happens if you change the collation ID in
  mysql-test/str_data/Index.xml to a value smaller than 256.
  
  Crash happened in SQL parser, because the "ident_map" and "state_map"
  arrays were not initialized in loadable utf8 collations.
  
  Fix: adding proper initialization of the "ident_map" and "state_map"
  members for loadable utf8 collations.
