Change Details

WIP do not review This version implements the policy after ConnectBlock but before the UTXO updates are flushed which gives the lowest risk compared to implementations that apply the policy before or after ConnectTip.

Moving the miner fund from consensus to policy makes it possible to do the following without a flag day upgrade: * Change fund address * Change fund amount * Add staking rewards This iteration of the patch (initial feedback in D12806) implements the policy after ConnectBlock but before the UTXO updates are flushed because alternatives are higher risk: * Before ConnectTip/ConnectBlock - Parking a block before checking consensus rules would prevent a node from banning peers sending invalid blocks. * After ConnectTip - Rewinding the in-progress state changes is fragile and prone to complications while backporting. After Wellington activates, the miner fund will no longer be enforced as a consensus rule. Blocks not including the miner fund will be parked and voted on by avalanche. Depends on D13150
