fix(android): suppress reflection for default animations (#6141)

Fixes `Error: java.lang.CloneNotSupportedException: Class android.support.v4.app.FragmentManagerImpl$AnimationOrAnimator doesn't implement Cloneable` in specific projects.

Related to #5785

BREAKING CHANGE


Before:
Default fragment enter animation was Android version specific

After:
Default fragment enter animation is now fade animation for all Android versions

You can customise the transition per navigation entry or globally via the [navigation transitions API](
