feat(ctb): tweak XDM storage layout

Improve the error message during genesis generation

Tweaks the storage layout of the CrossDomainMessenger base contract to
reduce the number of changes with the existing system. The
L1CrossDomainMessenger has no storage diff after this PR.

These are no longer used, in favor of the `op-node` commands
that generate the genesis files instead.

contracts-bedrock: delete imports

feat(ctb): make StandardBridge vars immutable

chore: Upgrade foundry

Updates the StandardBridge to use immutable variables instead of state
variables. Primary reason for this change is to guarantee that the
storage layout will not be a problem during the upgrade. Plus, there's
really no reason why these variables shouldn't be immutable.

Use `hardhat compile` so that it ensures that the artifacts
used by the generator are up to date

Moves the `GovernanceToken` into `contracts-bedrock`
so that its artifact can be easily inspected. This
is the first step in deleting `contracts-governance`.
The other files should be moved to `contracts-periphery`.

Every L2 predeploy that has `Semver` must be built so that it's
immutables are handled, even though they are hardcoded in the
bytecode.
