Use Ganache programmatically in e2e tests (#7664)

The `ganache.js` helper module uses `ganache-core` to start `ganache` instead of `ganache-cli`, and allows all of the same customization. Using `ganache` programmatically from our e2e tests is much faster, as we don't have to wait that arbitrary 5 seconds before each test as we wait for `ganache-cli` to start up.
