Name/Symbol should be empty since Enabled is false?

We may need to break this out into its own contract pending some open decisions on the rollout, will follow up as soon as possible

We will want to add a flag that enables the ability to set the amount of liquidity in the native asset liquidity contract so that it can be set to 0 for chains that would like that usecase |

Description
Enables OP Stack chains to use an asset other than ETH as their native fee currency by introducing a minimal, flexible, and standardizable Custom Gas Token (CGT) architecture. To do so, it introduces new predeploys (
NativeAssetLiquidityandLiquidityController) that decouple native asset management from core bridging operations while using a singleisCustomGasToken()flag that disables ETH transfer flows in all bridging methods. The two new pre-deploys manage the native asset supply.Tests
Core contracts:
OptimismPortalandL1Block: Tests forisCustomGasToken()flag blocking ETH deposits/withdrawalsNativeAssetLiquidity: Tests deposit/withdraw access control and functionalityLiquidityController: Tests minter authorization, mint/burn operations, and metadata functionsMetadata
