move ANDROID_APP to bevy_window (#15585)

# Objective

- Remove dependency in bevy_asset to bevy_winit
- First step for #15565 

## Solution

- the static `ANDROID_APP` and the `android_activity` reexport are now
in `bevy_window`

## Migration Guide

If you use the `android_activity` reexport from
`bevy::winit::android_activity`, it is now in
`bevy:🪟:android_activity`. Same for the `ANDROID_APP` static
