cannon: Add feature toggling to MIPS VM contracts (#15487)
* cannon: Add state version to MIPS contract. * Formatting. * cannon: Update EVM tests to init contract correctly. * Fix contracts checks. * op-deployer: Fix test * Formatting * Fix interfaces. * Update MIPS2 version. * cleanup: Cut println * Remove MIPS contracts from code freeze * Drop legacy MipsVersion 2 * Run semver-lock * Drop -beta suffix from version * Run semver-lock * cleanup: Reorganize MIPS64 imports --------- Co-authored-by: Adrian Sutton <[email protected]>
