Federico Caselli 3ebc3710a7 `Identity implies nullable=False`. ...

Altered the behavior of the :class:`_schema.Identity` construct such that
when applied to a :class:`_schema.Column`, it will automatically imply that
the value of :paramref:`_sql.Column.nullable` should default to ``False``,
in a similar manner as when the :paramref:`_sql.Column.primary_key`
parameter is set to ``True``.   This matches the default behavior of all
supporting databases where ``IDENTITY`` implies ``NOT NULL``.  The
PostgreSQL backend is the only one that supports adding ``NULL`` to an
``IDENTITY`` column, which is here supported by passing a ``True`` value
for the :paramref:`_sql.Column.nullable` parameter at the same time.

Fixes: #5775
