save nodes in distributor state

Because AccountLoader does not support storing a dynamic Vec directly. So, create CanopyTree to storage metadata (root, nodes, depth..) of MerkleDistributor

Flow for storage a part of proof onchain:
Note:
I quickly tested the NewClaimAndStake transaction locally using:
The resulting transaction size was 661 bytes. That means we have about 571 bytes of remaining space, which should accommodate roughly 17 proofs for this transaction in this case.
