Fixes a long standing bug that allows the batch submitter
to send batches that only contain deposit transactions.
Includes test coverage of the batch creation.

The on chain code requires that there must be at least one
context. A context contains information about the queue
transactions that should be included. It makes no sense
to error when there is a context but no sequencer txs
because the context must be submitted to the chain.

feat(packages/atst): Final touches on the docs

Remove the unchecked arithmetic in favor of lowering the
max base fee. This will prevent situations in which the
max base fee causes gas consumption greater than the
block gas limit.

When multiplying a uint64 and uint128 and assigning to
a uint256, the solidity checked math applies to the
types of the numbers being multiplied. This means that
solidity catches an overflow when the result of larger than
a uint128 even though its assigned to a uint256.
This PR uses unchecked math to prevent this kind of overflow
instead of casting the values to uint256 because it is
safe to use unchecked math here. The following inequality
always holds true, which shows that it is safe:

``` solidity
type(uint64).max * type(uint128).max < type(uint256).max
```

fix(ctb): Use `callWithMinGas` in the XDM

contracts-bedrock: fix gas benchmarks

Fixes the benchmarks by ensuring that the optimism portal
is initialized as well as ensuring that the prev base
fee is always explicitly set.

The previous benchmarks were pretty far off with their estimations.

contracts-bedrock: delete dead deployments

This is WIP because it doesn't perfectly re-assemble channels, but starts
to provide info on dangling channels.
