Feature: Android Pressable foreground ripple

[andreialecu]

Summary

Pressable does not support foreground Android ripples: https://reactnative.dev/docs/touchablenativefeedback#useforeground

This is needed for certain scenarios otherwise Pressable cannot be used, and users have to resort to TouchableNativeFeedback instead.

foreground is necessary when using react-native-linear-gradient for example, otherwise the ripple renders underneath the gradient and if used for buttons, it doesn't show any feedback.

react-native-linear-gradient/react-native-linear-gradient#64

Test Plan

@andreialecu How do you make the ripple effect with round corners? This is what I get:

Would this pull request fix this problem?

[andreialecu]

You need to add a wrapping view with the correct border-radius + overflow hidden.
