Rearrange CLUSTER rules in gram.y.
This change moves the unparenthesized syntax for CLUSTER to the end
of the ClusterStmt rules in preparation for a follow-up commit that
will move this syntax to the "Compatibility" section of the CLUSTER
documentation. The documentation for the CLUSTER syntaxes has also
been consolidated.
