Etherlink: use node's timestamp in simulation

What

Closes #7338 (closed)

The simulation currently use the last seen timestamp in simulation. Whereas the node can provide a sequencer.

Why

The simulation does not make sense if the contract relies on timestamp, it needs a proper value.

How

Introduces a new simulation version, that provides the timestamp. The tricky thing is to know which simulation version the kernel supports, to this purpose I have introduced a new empty storage version for the node to understand that it's supported. It's a bit weird, but works like a charm.

Manually testing the MR

Deploy a timestamp related contract and play with this!
