[Impeller] Draw Arc with sweep angle 0 causes app to crash

### Is there an existing issue for this?

- [X] I have searched the [existing issues](https://github.com/flutter/flutter/issues)
- [X] I have read the [guide to filing a bug](https://flutter.dev/docs/resources/bug-reports)

### Steps to reproduce

Use the example provided and change the progress value to 0.

### Expected results

App should not crash and should behavior like skia.

### Actual results

The app crashes and throws `null pointer dereference`.
