Stacked on !18679 (merged)

Linear issue

Closes L2-260

What

This MR adds support on the node for Tezlink batches.

It completes the batch support.

How

• Modify tezos operations in the Tx-queue to include first counter and length
• We create a verbose client in Tezt to log intermediate requests (useful for debugging)
• We add a test with multiple transfers
• We add a test with a reveal and transfer batch

Manually testing the MR

Two tests were added that can be executed with

dune exec etherlink/tezt/tests/main.exe -- tezlink /dal batch --verbose
