NoSuchFieldException in EntryRenderer

## 🐛 Bug Report

When building an Android app targetting API 29 or higher,` MaterialEntryRenderer` fails to get the `mCursorDrawableRes` field from `android.widget.TextView`, as it has been blacklisted.

https://github.com/Baseflow/XF-Material-Library/blob/fef56fb66de1ff7fc198745f200883f6ac489c20/XF.Material/Platforms/Android/Renderers/Internals/MaterialEntryRenderer.cs#L74

I guess it also break the cursor colour change, but I haven't tested that.

I found [this issue here](https://github.com/unoplatform/uno/issues/6240) with the exact same problem, and a proposed solution.

### Expected behavior

The code should not throw a `NoSuchFieldException` here.

### Reproduction steps

Create a project with a MaterialLabel, and the Android target API >= 29. Then run it in debug mode (I am using Rider). An exception should be caught by the debugger.

### Configuration

**Version:** 1.8.0
