[tarantool-patches] [PATCH 2/2] sql: remove unused SQLITE_CONSTRAINT_ error codes

[AlexeyIvushkin <ivushkinalex@gmail.com>]

From: Morgan-iv <ivushkinalex@gmail.com>

Remove SQLITE_CONSTRAINT_ error codes that only defined, but don't used
anywhere. Change its implementation from define macro to enum statement.

Part of #3315
