FR: Module -> Module contribution

[ZacSweers]

A common case I've run into is wanting to have modules contribute to other modules, rather than components. I often use modules that are intentionally reusable, and generating a module that contributes to them would be immensely helpful.

@Module
class DataModule { .. }

@Module
@ContributesTo(DataModule::class)
class VariantDataModule { .. }

// Results in 
@Module(includes = [VariantDataModule::class])
class DataModule { .. }

There is an annotation for this @MergeModules and @MergeInterfaces. Does this solve your use case?

@MergeModules(AppScope::class)
abstract class AppModule

This annotation will generate the annotation @dagger.Module.

Looks like it! Will dig and re-open if need be
