fix: OverKeyboardView compatibility with RN 0.72 (#658)

## 📜 Description

Added `RootViewCompat` interface to prevent build issues on RN < 0.72. 

## 💡 Motivation and Context

Prior to RN 0.73 `RootView` marked `onChildStartedNativeGesture(ev:
MotionEvent?)` as deprecated, but without default implementation, so if
you use `RootView` you had to override two methods:
- `onChildStartedNativeGesture(ev: MotionEvent?)`
- `override fun onChildStartedNativeGesture(childView: View, ev:
MotionEvent)`;

To fix this problem I decided to introduce common `RootViewCompat`
interface that will have a stub for deprecated method.

The reason why I moved it to separate file was mostly following SOLID
principles - potentially this interface can be re-used in other parts of
application, and I can not implement method directly in
`OverKeyboardRootViewGroup` because I'll exceed maximum methods amount
(11+).

Closes
#657
