SQL: Define primary key for tables without it (#22255)

Browse Source 
The annotation_tag and alert_rule_tag tables did not have
PRIMARY KEY defined what cause problems with migration to
MariaDB with Galera setup with
 innodb_force_primary_key=1
Or MySQL > 8.0.13 with
 sql_require_primary_key=ON

Which can manifest as follows:

MariaDB
Error 1173: This table type requires a primary key

MySQL
ERROR 3750 (HY000): Unable to create or change a table
without a primary key, when the system variable 'sql_require_primary_key' is set.

Fixes #12971
