Pull Request Overview

This PR updates the gas cost for the CLZ (Count Leading Zeros) instruction in the Ethereum Virtual Machine from 3 to 5 gas units for devnet3, aligning with the specification changes in EIP-9987.

Adds explicit gas cost definition for the CLZ instruction using the GasCostOf.Low constant
