Implement contract testing in create fuels

[danielbate]

create fuels aims to provide a full stack and feature complete solution for working with and deploying dApps on fuel.

We should provide a contract testing solution so that consumers test their contracts in isolation. We should utilise forc test to keep the tool within the ecosystem.

How do you see all the different tests we'll provide?

Thinking out loud about the terminologies.

{
  "test": "run-s test:*",
  "test:unit": "forc test",
  "test:e2e": "vitest ..", // launchTestNode
  "test:ui": "vitest ..", // playwright
}
