IMPALA-13900: Exempt enable_tuple_cache_verification from tuple cache key
The tuple cache key includes all query options that are not
explicitly excluded. This currently includes enable_tuple_cache_verification.
It is useful to be able to run queries back to back with
enable_tuple_cache_verification=true vs false with the same
cache entry. This exempts enable_tuple_cache_verification from the
tuple cache key.

>
> Tuple caching include enable_tuple_cache_verification in the tuple cache key.
> I think it would be better to exempt it. If we exempt it, then running with
> or without verification will produce the same cache key, which is useful for
> local debugging.
