Replace ethers with viem in vm examples/tests

[acolytec3]

ethers currently is using an older version of @noble/hashes (v1.3.2) which is causing some duplication of versions of @noble/hashes in our monorepo.

ethers is only being used in vm for some ABI encoding/decoding utilities in 2 examples and one test so this replaces it with viem which has no dependencies and provides basically drop-in replacements for those tools.

Note, the robots wrote the actual translations of these functions and I reviewed/edited/tightened things up.
