Etherlink/Kernel/Tezlink: Change the evm_node behavior depending on the l2_chain experimental feature

Previous MR

!17298 (merged)

What

Previous MR introduced the chain_family notion in the EVM node to change the behavior of the node if we are in tezlink mode or etherlink mode. But to not break anything the previous MR forced the node in Etherlink mode, this MR does what needs to be done to switch between etherlink mode or tezlink mode.

Why

How

The first commit of the MR correct the kernel hash function that was not working with the one implemented in the node. Use the experimental feature l2_chain to replace the forced EVM chain family We also need to disable the pop_transactions of the tx_pool if we are in Tezlink mode
