feat(e2e): add an E2EController to each sample app

[kieran-osgood-shopify]

What changes are you making?

Previous PR added classes to handle parsing deep links for e2e scenarios
This one adds a controller for E2E that utilises the parser to receive the intent, and then dispatch the actions we need in the sample after

React Native already had most of the wiring as we set them up first so this PR brings kotlin and swift up to speed on wiring in the entry points for deep links into the E2EControlLink classes from PR #554

How to test

These things aren't wired up yet so nothing really to test, just dividing up the work
