[webview_flutter] Minor test cleanup (flutter#6031)

- Remove an iOS-only integration test from the app-facing package; there's already a copy in the iOS implementation package, and it's not relevant to the app-facing API.
- Remove dead iOS native test code; the actual iOS native tests are all in the iOS package now, and this code isn't being run (since the repo tooling doesn't try to run native tests for plugins that don't have inline native implementations)

Fixes flutter/flutter#91004
