Copy App_Resources directly to platforms/.../res (Android) or platforms/.../Resources (iOS)

[sis0k0]

Current behaviour
Currently, the App_Resources directory is copied from the root of the project (usually my-project/App_Resources or my-project/app/App_Resources) to the native assets (my-project/platforms/.../assets/app).
After that, the resources from the native assets are copied to their regular locations in the native project (e.g. my-project/platforms/../main/res).

Describe the solution you'd like
The first step can be skipped and the resources can be copied from the root of the project (e.g. my-project/App_Resources) to the native project (my-project/platforms/.../main/res) directly.

Additional context
When building with the --bundle flag, the initial copying is performed by the CopyWebpackPlugin.
