[Android] Empty title / message in Alert.alert causes extra spacing

Description

On Android, passing an empty string ("") for either the title or the message in Alert.alert results in visible empty space being rendered in the dialog.

Steps to reproduce

Case 1: Empty title

Alert.alert("", "Message", [
  { text: "OK", onPress: () => {} },
]);

Case 2: Empty message

Alert.alert("Warning", "", [
  { text: "OK", onPress: () => {} },
]);

Case 3: Both empty

Alert.alert("", "", [
  { text: "OK", onPress: () => {} },
]);

Screenshots and Videos

从必需的 Snack reproducer 开始，检查 Alert.alert 的 Android 实现。验证标题为空、消息为空以及两个值都为空时的行为，然后跟踪导致额外间距的对话框布局。当这三种情况都能在没有非预期空白的情况下渲染，并且该行为已由回归测试覆盖时，即视为完成。
