feat: support atomic deployment / batch submit

### Component

Forge

### Describe the feature you would like

I would like to batch-submit deployment script transactions within the same block. With this feature, users can deploy two contracts, execute multiple txs, atomically.

From my current understanding, each tx is submitted individually. This could cause problems on a multi-step deployment where action B should only succeed if the state changed from action A remains constant, but the contract is built in a way such that the state can be modified during/afterwards.

### Additional context

_No response_

Start by tracing how Forge deployment scripts submit transactions individually. Define the batching and atomicity requirements for deploying multiple contracts and executing multiple transactions within one block. Done means a deployment script can submit the batch so the operations succeed or fail atomically.
