Bridgeless-context ExtraWindowEventListenerTest (#59282)

Summary:
Pull Request resolved: #59282

Migrate `ExtraWindowEventListenerTest` from the deprecated
`createCatalystContextForTest` helper to `createTestReactApplicationContext`,
so the test builds a bridgeless context directly. Stub the feature flags
before context creation, since the bridgeless context reads them during init.
