Do not destroy views when there is a touch going on for New Architecture (#45865)

Browse Source 
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/45865

This diff introduces the logic to defer the destruction of ViewState (and EventEmitter) for views that are currently touched on by the user. The idea is to let the UIManager know which view is currently active from the `JSTouchDispatcher` and eventually defer the view deletion till the view is not interacted anymore.

The JSTouchDispatcher already retains the information on which tag was the touch originally fired.
We'll pass over that information to the UIManager/SurfaceMountingManager so that it can be accounted for when the view has to be deleted.

This is causing a couple of bad bugs on Android:

Fixes https://github.com/facebook/react-native/issues/45126
Fixes https://github.com/facebook/react-native/issues/44610
Closes https://github.com/facebook/react-native/pull/45675

Changelog:
[Android] [Fixed] - Do not destroy views when there is a touch going on for New Architecture
