Updated the localization tests so that they'll DTRT when useMaterial3:true becomes the default for ThemeData. In a few cases there are M2 and M3 tests now, to check features that are significantly different in Material3, notably the double ring for the 24 hour input dial. | Material 2 | Material 3| |---------|---------| | <img width="250" alt="Screenshot 2023-06-08 at 10 47 37 AM" src="https://github.com/flutter/flutter/assets/1377460/6ca95e22-b3f1-4f6b-9e39-79c888ba58f1"> | <img width="257" alt="Screenshot 2023-06-08 at 10 47 13 AM" src="https://github.com/flutter/flutter/assets/1377460/19b685bf-c812-4c87-baed-70fa56efaad8"> | In M3, most aspects of the ideographic text styles are the same as for alphabetic styles, so there are some tweaks here to account for that.
