fix(katana): l1/l2 messaging hash computations

[kariy]

Description

l1 -> l2 messaging should be using a different hash computation, but instead we were using the hash computation for l2 -> l1 message.

this pr adds a new compute_l1_to_l2_message_hash function for computing the hash of a l1 -> l2 message.
