Bug #51976 LDML collations issue

Browse Source 
Problem: caseup_multiply and casedn_multiply members      
were not initialized for a dynamic collation, so          
UPPER() and LOWER() functions returned empty strings.      
Fix: initializing the members properly.

Adding tests:
  mysql-test/r/ctype_ldml.result
  mysql-test/t/ctype_ldml.test

Applying the fix:
  mysys/charset.c
