Commit 0156e97560 ("storage_proxy: cas: reject for
tablets-enabled tables") marked a bunch of LWT tests as
XFAIL with tablets enabled, pending resolution of #18066.
But since that event is now in the past, we undo the XFAIL
markings (or in some cases, use an any-keyspace fixture
instead of a vnodes-only fixture).
Ref #18066.
Closes scylladb/scylladb#28336
