Set an in-protocol cap for the gas limit

Set an in-protocol cap for the gas limit of 30,000,000.
A high gas limit increases pressure on the network. In the benign case, it increases the size of the state and history faster than we can sustain. In the malicious case, it amplifies the devastation of certain denial-of-service attacks.
As of the fork block

The gas limit is currently under the control of block proposers. They have the ability to increase the gas limit to whatever value they desire. This allows them to bypass the EIP and All Core Devs processes in protocol decisions that may negatively affect the security and/or decentralization of the network.
A valuable property of proposers choosing the gas limit is they can scale it down quickly if the network becomes unstable or is undergoing certain types of attacks. For this reason, we maintain their ability to lower the gas limit below 30,000,000.
No backwards compatibility issues.
