Disable OverlappingRendering for ReactTextView

Summary:
This diff disables OverlappingRendering for ReactTextView to avoid the exception:

```
java.lang.IllegalStateException: Unable to create layer for com.facebook.react.views.text.ReactTextView
```
during fade animations

OverlappingRendering enables an optimization during rendering of animations per component, disabling this might affect performance of animations inside TextView.

We will add a ReactFlag to experiment on how this affect other surfaces.
