[ethereum_abi_annotator] Implement an adapter to convert between Move and ethereum encoding

[runtian-zhou]

…reum encoded data and move encoded data.

Motivation

Implement an adapter to allow interacting with Move world with ethereum style api. There are two major components:

1. An event annotator. The goal here is to convert the event emitted by MoveVM into log format used in the ethereum ecosystem, including both the encoding and the topic hash.
2. A call data annotator. The goal is to convert an eth call data into parameters into invokations into MoveVM's session and also a function to encode the Move value into ethereum's encoding.

The apis needs a lot more tuning on error propagation. This PR just serves as a proof of concept for now.

I'll add an example later on how to use those apis. The final goal is to implement a ERC20 contract with Move.

Test Plan

Will add an example demonstrating how the annotator should work.
