Use ECDSA/k256 for sov signatures

[ercecan]

Description

Uses k256 after fork2 instead of dalek signatures

With this pr we will be getting rid of sha 512 after fork2 and we will be using k256 signatures.
Main reason to do this is ABOUT 10% our cycles are coming form Dalek signatures and sha512, and risc0 has k256 accelerator so our cycles will drop quite a bit.

with 3055 txs in around 15 blocks we can see ~3.5% drop in cycle counts, this drop will be much more in real scenarios when txs are more spread to more blocks, instead 3000 txs being compressed to 15 blocks like in this case.
