Set the CV2 handlers as the default

[Ahamed-Ali]

Description of Change

To make CV2 handlers the default, set cv2handlers to true.

(i.e) when we use CollectionView / CarouselView = > CollectionViewHandler2 and CarouselViewHandler2 are used by default.

Explicitly setting CollectionView1/CarouselView1 or CollectionView2/CarouselView2 will configure the corresponding handlers correctly, as before.

Pull request overview

This PR makes CollectionViewHandler2 and CarouselViewHandler2 the default handlers for iOS and MacCatalyst platforms in the test host app. When developers use CollectionView or CarouselView in tests, they will now get the V2 handlers by default instead of V1 handlers.

Key Changes

• Changed the default cv2Handlers flag from false to true for iOS/MacCatalyst test configuration
• The environment variable override mechanism (TEST_CONFIGURATION_ARGS) remains functional for tests that need to explicitly control handler versions

we need to update the TEST_CONFIGURATION_ARGS setting as well in the yaml files

Can you make it so that CollectionView1 is now a separate test lane and CollectionView2 is the one that runs in the normal stage?

The changes on this Pr just make it so we are only testing CollectionView2

I have modified the TEST_CONFIGURATION_ARGS in the ui-test.yaml file so that CollectionView1/CarouselView1 run in a separate lane, and CollectionView2/CarouselView2 run in the main lane. Please let me know if you have any other concerns. @PureWeen
