op-node: Add the Generic Commitment Type

[trianglesphere]

Add support for DA commitment type 1, da-service commitment inside op-node. No validation should be done. It does not need to reach out to the DA server yet.

The purpose of this ticket is to simply create the type that the op-batcher + op-node will use.
