Implement Cargo Stylus Developer Tool

[rauljordan]

See the design document here

Overview

This PR implements the cargo stylus developer tool's foundations, with two subcommands to start with:

cargo stylus check: checks if a contract can be brotli compressed to <= 24kb and if it can compile correctly onchain by using an eth_call with state overrides
cargo stylus deploy: attempts to submit deploy + compile txs for a stylus program to an Arbitrum backend. A user can also choose to separate out both steps, or just run gas estimates.

The deploy function creates a local signer based on either a private key file or a keystore path and keystore password file path

How to Try It

Inside the cargo-stylus folder:

cargo install --path .

To try the PR, another branch exists called test-cargo-stylus with a Stylus system test which just spins up a node which hangs forever, exposing an HTTP RPC endpoint at localhost:9999. This means the CLI tool can be used to perform these actions.

Run it with:

go test ./system_tests -run=TestStylusCargo -v

The branch is test-cargo-stylus. Navigate to any arbitrator/stylus/tests/ folder, then save the deployer private key (ArbOwner test fixture) in a file called privkey

009f3fd6848015f83b9210c89f7744e3941acae1195c8bf9f5798c090dc8f497

then run:

cargo stylus deploy --private-key-path=privkey --endpoint=http://localhost:9999
