memtx: raise an error when trying to use unsupported MVCC feature

Memtx MVCC does not support multikey indexes, but allows to use them.
If one will use them, Tarantool is most likely to crash, and that's the
best scenario - otherwise Tarantool will work, but something terribly
wrong will be happening under the hood. Let's simply forbid to create
such indexes along with MVCC until we support them.

In addition to that, the commit forbids to create functional indexes
along with memtx MVCC enabled since target Tarantool version for this
commit does not support them completely.

Workaround for #6385
