Move DisputeGame creation to Creator Contracts

[ControlCplusControlV]

Description

Introduces a Creator pattern for dispute games that decouples chain-specific configuration from game implementations, allowing multiple chains to share the same implementation contracts while maintaining their unique configurations. The change moves immutable variables into creator contract storage and adds a new abstraction layer between the factory and game implementations. This simplifies deployment workflows, reduces gas costs for new chain onboarding, and provides better upgrade paths for chain-specific configurations.
