Update manual_tests to be able to run on macOS/web (#44830)

I updated the build files for manual_tests, as well as adding in a macos and web directory to allow the manual tests to be run on the web or on desktop.

The main change here are the parts that I added to the files in manual_tests/lib/... (the addition of kIsWeb to "if (!kIsWeb && Platform.isMacOS) {") The rest is just an update of the auto-generated code from flutter create.

+You can customize the launch screen with your own desired assets by replacing the image files in this directory.
+
+You can also do it by opening your Flutter project's Xcode project with `open ios/Runner.xcworkspace`, selecting `Runner/Assets.xcassets` in the Project Navigator and dropping in the desired images.
