This PR allows the owner of the `OVM_GasPriceOracle` to send transactions with 0 gas price when the enforce fees config option is turned on. The L2 gas price is currently updated by sending transactions to the chain to a special contract. In the future it should be updated as a side effect of transaction execution. Having the gas price on chain is important so that it can be replicated accross the network to ensure that users can send transactions with a high enough fee. Having the `OVM_GasPriceOracle.owner` key not need to maintain ETH on L2 is an operational simplification as well prevents a terrible scenario where a bug causes the L2 gas price to go so high that it is impossible for the owner to update it.
