[FR] Android dependencies should target main gradle or launcher template.

### Feature proposal

* EDM4U Component: Android Resolver

Since Unity 2019.3, they changed their build system to build the main project as library. There are now 3 gradle scripts, base, launcher and main library. EDM4U still does library resolving on mainTemplate only and doesn't allow you to add dependencies to the launcher script. Please add a way in the Dependencies.xml files to specify which gradle script to target. For example, add an attribute: .

We're requesting this because recently an SDK that we rely on had to move their plugin and dependencies to the launcher-level and not the main Unity library. This makes it difficult to maintain multiple Android build configurations because we can no longer use EDM4U's great Dependencies.xml system.
