These are stripped down versions of the original contracts that can be
dropped in place via an upgrade to disable core functionality.
Governance features are still enabled, which means it's possible to
upgrade back to a working implementation.
Added a `uint256 evmChainId` state variable to the Core, Token and NFT Bridge
contracts. `evmChainId` is compared to `block.chainid` in the `chainId`
function. When they don't match, a "bad fork" Chain ID is returned,
otherwise the Wormhole Chain ID is returned.
