Fix CursorDrawable Color Tint for Android 10+

Browse Source 
Summary:
Accessing this field via reflection is explicitly blacklisted by Google in Android 10 and higher. They have provided a new API to change the color, which I have implemented here. [The old setColorFilter is deprecated](https://developer.android.com/reference/android/graphics/drawable/Drawable#setColorFilter(int,%20android.graphics.PorterDuff.Mode)) so I also updated that method call as well.

Changelog: [General] [Fixed] Use new setTextCursorDrawable API for Android 10
