Pressability: Consistently Fire onPress{In,Out} w/o onPress

Summary:
Currently any component using `Pressability` is quickly tapped and released (i.e. responder grant followed only by reponder release), we fire `onPressIn` and `onPressOut` immediately to ensure that any visual feedback for the interactive element is momentarily visible.

Currently, we were mistakenly skipping this logic if `onPress` was null.

This fixes it so that we fire `onPressIn` and `onPressOut` consistently, even if `onPress` is null.

Changelog:
[General][Fixed] - Pressability now consistently fires `onPressIn` and `onPressOut`, even without an `onPress`.
