What is the current behavior?

On Android, icons rendered in TabView and Actionbar are not scaled correctly due to the use of a deprecated native Android constructor https://developer.android.com/reference/android/graphics/drawable/BitmapDrawable#BitmapDrawable(android.graphics.Bitmap).

On iOS, there was no property on ActionBar to specify icon rendering mode and it is hard coded to alwaysOriginal, which made the use of image icons limited.

What is the new behavior?

Fixed the Android issue with the use of the new constructor.

Added iosIconRenderingMode on ActionBar. To avoid breaking changes, on ActionBar this property defaults to alwaysOriginal and on TabView, it defaults to automatic. We should probably change this for 6.0.

Fixes #5887
