feat(itests): remove Watcher from fundUser

This commit removes the deprecated Watcher class from the fundUser
function in favor of using the CrossChainMessenger class from the new
Optimism SDK. This is part of a series of commits that are designed to
eventually remove the Watcher entirely from the integration tests (and
then from the entire repository).
