Nadav Har'El f50db50d10 test/cql-pytest: test for "WHERE v=NULL" in restrictions

Issues #4476 and #8489, and also Cassandra's CASSANDRA-10715, all request
that filtering with "WHERE v=NULL" should return the rows where the column
v is unset. However, we made a deliberate decision to do something else:
That "WHERE v=NULL" should match no row. Exactly like it does in SQL.
This is what this test verifies - that "WHERE v=NULL" never matches any
row - not even rows where "v" is unset.

This test is expected to fail on Cassandra (so marked cassandra_bug),
because in Cassandra the "WHERE v=NULL" restriction is forbidden,
instead of succeeding and returning nothing.

Although we differ here from Cassandra, after a lot of deliberation we
decided that Scylla's behavior is the correct one, so this test verifies
it.

Refs #4776.
Refs #8489.
