MDEV-8582: innodb_force_primary_key option does not force PK or unique key

Browse Source 
Analysis: Handler used table flag HA_REQUIRE_PRIMARY_KEY but a bug on
sql_table.cc function mysql_prepare_create_table internally marked
secondary key with NOT NULL colums as unique key and did not then
fail on requirement that table should have primary key or unique key.
