kona-sp1: Ensure expensive operations are offloaded to the host

For evm operations, the kona-sp1 program installs a custom implementation of cryptographic operations via revm hooks. The custom implementation is optimized for the sp1 zkVM.
However, there are still a couple areas where the program runs keccak and sha2 outside the evm. We need to ensure that these don't use native riscv implementations, but utilize the sp1 host via its syscall interface.

No files or tests are named. Start by tracing the keccak and sha2 call sites in kona-sp1 and comparing them with the existing revm cryptographic hooks. Done means these operations use the SP1 host syscall interface instead of native RISC-V implementations.
