Fixes https://github.com/dart-lang/sdk/issues/62234 by making the 'dart:ui' library discoverable in the same way that the real one is discoverable: by the sky_engine _embedder.yaml file. Coupled with this change is the motivation: the stubs are out-of-date, with `double width` and `double height` parameters on the Preview constructor. But this has been changed to use a `Size` object, and `Size` is written in 'dart:ui'. So to write a test that uses `Size`, the test now needs proper access to 'dart:ui', and we should not write 'package:ui/ui.dart' in our test cases. These changes are in `.../lib/mock_packages/package_content/flutter/lib/src/widget_previews/widget_previews.dart` and in `invalid_widget_preview_private_argument_test.dart`.
