`SELECT` commands with SERIAL consistency level are historically allowed for vnode-based views, even though they don't provide linearizability guarantees and in general don't make much sense. In this PR we prohibit LWTs for tablet-based views, but preserve old behavior for vnode-based views for compatibility. Similar logic is applied to CDC log tables.
We also add a general check that disallows colocating a table with another colocated table, since this is not needed for now.
