Removes rebalancing from the PCV Deposit Aggregator.
Rationale: pcv deposits should be as firewalled from each other as possible, so that one compromised or malicious pcv deposit can't rug all tokens in the aggregator.
By removing the rebalance feature, we effectively only allow rebalance-on-push and rebalance-on-withdraw; deposits and withdrawals will still deposit and withdraw, respectively, from each pcv deposit to average the underlying tokens towards their weights, but there will be no atomic interaction that allows pcv to flow from one pcv deposit into another.
Withdraw is still permissioned, of course; a hacker couldn't withdraw from one pcv deposit and then call deposit() to deposit into another.
depositSingle(address pcvDeposit)has replacedrebalanceSingle(address pcvDeposit), and permission for this has been set to GuardianOrAdmin, though I'm up for changing this if warranted.
