Ensure alert dialog title wraps to two lines, uses default style (#47095)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/47095

The [internal `DialogTitle` implementation from Android](https://cs.android.com/android/platform/superproject/main/+/main:frameworks/base/core/java/com/android/internal/widget/DialogTitle.java;l=63?q=DialogTitle) makes additional checks to see if the title should wrap to two lines before applying ellipsis, so this change recreates those same checks. This change also removes the text appearance and size changes made to the layout.

Reverts some of the changes made to https://github.com/facebook/react-native/pull/45395.

**Changelog:**
[Android][Fixed] - Fixed styling on alert dialog titles to wrap two lines and retain bold appearance
