op-test-sequencer: support for L1 reorgs

[nonsense]

Description

This PR is:

1. Adding builder/signer/publisher/sequencer for L1 to the op-test-sequencer, enabling it to produce L1 reorgs
2. Adding a test that triggers a L1 reorg, and checks if eventually the L2 chain is also reorged and uses valid L1Origin references, and does not reference reorged L1 blocks.

TestL2ReorgAfterL1Reorg looks good to me.

Gave a first-pass review (excluding the newly added op-test-sequencer code). Will do a second review as a follow-up to cover that part.
