[Android] Incorrect border coloration with sufficiently high border radius

Description

It seems Android has trouble displaying the correct border colors when borderRadius exceeds a certain value.

The use case here is having an easily reusable style or component which can be circular regardless of the size; most easily achieved by setting a high border radius. Given that this works as intended on iOS and web, I assume it is a supported use case. If border radius is not intended to exceed a certain calculable value it should be noted in the docs somewhere but I was unable to find any relevant information. Alternatively, It might make sense to clamp the value in the RN core code but I'll leave that to the maintainers to decide.

Based on my testing this issue only impacts Android as you can see in the screenshots from the snack I've linked below.

I've seen some other recent issues around border radius on Android but none of them seem to be directly related to this particular behavior based on my understanding so apologies if this is a duplicate, obviously feel free to close/merge in that case.

Steps to reproduce

1. Create a <View />.
2. Give the view different colors for each of borderTopColor, borderBottomColor, borderRightColor, and borderLeftColor
3. Set the view's height and width to any number, n
4. Set the view's borderRadius to any number greater than n/2
5. Observe the coloration of the border. Optionally, you can change the borderRadius value to see how the colors change with different values.

まず、リンクされた Snack を実行し、異なる境界線の色と、View のサイズの半分より大きい borderRadius を使って Android の動作を再現します。次に、Android における React Native の border-rendering のエントリポイントを追跡し、その後 iOS と web のスクリーンショットと照合して結果を確認します。報告された radius のケースで Android の境界線の色が正しいままであれば完了です。
