We currently allow creating multiple vector indexes on one column. This doesn't make much sense as we do not support picking one when making ann queries. To make this less confusing and to make our behavior similar to Cassandra we disallow the creation of multiple vector indexes on one column. We also add a test that checks this behavior. Fixes: VECTOR-254 Fixes: #26672 Closes scylladb/scylladb#26508
