all: Remove cannon-kona dgv2 feature flags

[Inphi]

This PR removes the CANNON_KONA and DEPLOY_V2_DISPUTE_GAMES dev feature flags and makes their behavior the default.

Unresolved Issues

• Should we maintain deploy scripts for V1 dispute games? These scripts may yet be useful for chains that haven't upgraded. While they will always be available in older op-deployer releases, it's quite convenient for the latest op-deployer to support them.

@Inphi carrying forward the scripts seems like a nice feature to me
