[native assets] Build dev dependencies in flutter test integration_test (#170374)
Closes: https://github.com/flutter/flutter/issues/168961

This PR ensures the build hooks of `dev_dependencies` are run on
`flutter test integration_test`.

`flutter test` already builds dev dependencies. However,
`package:integration_test` is using `flutter assemble` which should not
have dev dependencies included (`flutter build` should not bundle dev
deps).

~~So, this PR adds a build define that's threaded through from `flutter
test` to `flutter assemble`. It's threaded through gradle and xcode via
`BuildInfo` and subsequently read in tool backend where it is added as
an `Environment` define. Finally it is read in the `Target` that builds
the native assets.~~

~~One quirk is `flutter run test integration_test -d flutter-tester`.
(No idea why someone would run that, but it works.) This doesn't spin up
Gradle or XCode. So the environment is set directly.~~

Edit: We use the simpler `kBuildMode` to decide whether to include the
native assets for dev dependencies.

## Testing

* The desktop OSes and `flutter-tester` are tested in
`packages/flutter_tools/test/integration.shard/isolated/native_assets_test.dart`.
* iOS simulator, device, and Android device are tested in the device
lab.
* (All tests were added to existing tests, hopefully these don't start
timing out.)
