refactor(plugin-htlc-eth-besu): stop using the deprecated api.encodeP…

…acked

1. Add tests to vanilla HashTimeLock
2. Replace abi.encodePacked by abi.encode
3. Compile and replace generated ABIs (for HashTimeLock and PrivateHashTimeLock)

Peter's additional changes:
1. Replace all the function calls that were missed.
2. Also update the hash function from sha256 to keccak256 where it was missed
3. Recompile the contracts again but with the VScode extension that gives them
the additional properties with their metadata like the contract name that we
use during deployment.
4. Modify the test case so that it computes the hash for the contract ID
purely in Javascript instead of doing a call to the EVM to do the same.
