upgrade: allow DDL before box.schema.upgrade is called

During upgrade process user always checks, whether his code works on
the new version of Tarantool before calling box.schema.upgrade. However,
since we prohibited DDL before upgrade is done, it's difficult to do so,
since config module cannot give permissions, user needs, cannot assign
names. The latter usually breaks external modules, which expect names to
be set.

It was decided to partially allow DDL before upgrade. Since now on, we
will explicitly forbid new features for old schemas. However, the
majority of the features will remain allowed, e.g. it's allowed to
create persistent function, but not persistent trigger, when upgrading
from 2.11.1.

DDL is allowed only if schema version is >= 2.11.1. Before this point
all DDL before schema upgrade remains forbidden.

Closes #10520

@TarantoolBot document
Title: Allow DDL before box.schema.upgrade
Since: 3.3.0

From now on, DDL before schema upgrade is allowed for schema versions >=
2.11.1 (previously it was forbidden in 3.0.0 release). In documentation
we need to create a list of features, which are forbidden until some
versions. Current state:

* DDL before box.schema.upgrade - forbidden until 2.11.1
* Persistent names - forbidden until 2.11.5
* Persistent triggers - forbidden until 3.1.0
