Infra - change Dialog to use reanimated 2

Description

Infra - change Dialog to use reanimated 2.
Note that this has Infra/reanimated-2-part-1-refactor-dialog set as base and not master.
Known issues:
Android - gestures do not work (only the animation works), this is probably because we need to add gestureHandlerRootHOC or GestureHandlerRootView somewhere (I did not find the correct way to do it).
Android & iOS (more visible on Android): the view is shown for a short time in the "visible location" before animating in from the "hidden location" fixed with persistentAnimationValue, not sure if that's the best solution.
I'm not sure I've solved all the errors from migrating to v2.

@M-i-k-e-l
I split your PR into two
#1223 - Only migrating the demo project intro reanimated v2, the is now enough for migrating since reanimated handle gracefully the migration. But it does throw warnings.

#1224 - Migrate all of the component that use Reanimated to use the new API with a fallback to the old one. This way our users can gradually migrate when they are ready. And if someone install reanimated v2 they won't get the annoying warnings.

Anyway, I separated it from the dialog changes.
Also, I didn't handle Incubator.TabController, since we plan to deprecate it.
