Remove `@metamask/controllers` > `babel-runtime` from direct dependencies

[mikesposito]

babel-runtime package is included in multiple @metamask/controllers' direct deps: It is unused but takes up bundle size.

[legobeat]

babel-runtime is still used by ethjs packages and therefore also through eth-method-registry. Recent @metamask/ethjs forks remove the babel-runtime (peer)Dependency.

Below PRs aim at resolving this.
