[Tarantool-patches] [PATCH v1 2/3] sql: use field_type_MAX instead of FIELD_TYPE_ANY

[Mergen Imeev via Tarantool-patches <tarantool-patches@dev.tarantool.org>]

After this patch, the built-in SQL function implementation definitions
will use field_type_MAX to indicate that they accept values of any type,
instead of FIELD_TYPE_ANY.

Part of #3174
