Incomplete implementation of android dynamic features

We're migrating our Android codebase to Bazel, and are using android dynamic features module containing resources, assets and bytecode.

However, bytecode in dynamic feature is not supported at the moment. See [comment](https://github.com/bazelbuild/rules_android/blob/315d094cb61001416e8b1a83963c979f2e2f1d49/rules/android_application/android_feature_module.bzl#L52) : `the `android_library` contained in this split. Must only contain assets.`

It's unclear if android resources are supported either.
