In SQL, it is allowed to use vector expressions, that is, an
operation that uses vectors as operands. For instance, vector
comparison:
SELECT (1,2,3) < (1,2,4);

Accidentally, routines handling IN operator contained a bug: in
cases where we used a vector as the left value in the IN operator,
we received an assertion in debug build or a segmentation fault in
release. This was due to some legacy code in which it was assumed
that the left value of the IN operator can have only one column in
case it is a vector. Let's fix this by allowing vectors of the
other sizes as the left value of the IN operator and providing
check which verifies that both sides of IN operator have the same
dimension.

Closes #4204
