Multimodule scan for definitions

[arnaudgiuliani]

Generate definitions as external if not captured in a local module, to be scanned by an external module later.

Those external definitions are functions, that can be called in other modules. They are generated in Default file, where it can be imported via @Definition annotation.

Examples apps are updated with such use. Like:

package org.koin.sample.androidx.data

@Factory
class DataConsumer

will be scanned by in another Gradle module:

@ComponentScan("org.koin.sample.androidx.data")
class DataModule

Generated code in Default file, to be scanner by compiler:

@Definition("org.koin.sample.androidx.data")
fun Module.defineDataConsumer() = factory() { org.koin.sample.androidx.data.DataConsumer() }
