Do not enforce fixed partitioning in Hive connector

[sopel39]

Engine will ensure that consecutive buckets are assigned
to shuffled nodes, therefore it's not needed to explicity
provide that by connector

This essentially reverts 9558ff4. I honestly cannot remember why I've added that in the first place

Only io.trino.sql.planner.NodePartitioningManager#getNodePartitioningMap and io.trino.sql.planner.NodePartitioningManager#getBucketNodeMap use io.trino.spi.connector.ConnectorBucketNodeMap#hasFixedMapping and they assign same shuffle mapping when when explicit connector mapping is not present
