[PATCH 05/12] vinyl: move vy_tuple_key_contains_null to generic code

The function doesn't require any knowledge of vinyl statement layout and
can work on regular tuples. Let's rename it to tuple_key_contains_null,
move its implementation to tuple_extract_key.cc, and declare it in
key_def.h, as we do with other similar functions.
