Migrate remaining plugins to AndroidX (#1115)

The original Android support libraries have been deprecated in favor of
AndroidX. This migration shouldn't affect behavior in a user noticeable
way, but does require plugin users to also migrate their app. See
[migrating to AndroidX](https://developer.android.com/jetpack/androidx/migrate).

Fixes flutter/flutter#23995.
