Include sources for scala-java8-compat instead of jar

This reverts commit e1895d64f87dc3c699a3ccbc8a3143b18d3b5bb1,
titled "Add scala-java8-compat to scala-library.jar".

Move SAM functions and `LambdaDeserializer` (from scala/scala-java8-compat@9253ed9)
into `scala.runtime.java8` package under `src/library`.

(The package name is the only diff -- they were in `scala.compat.java8` before).

The original LambdaDeserializer:
https://github.com/scala/scala-java8-compat/blob/c0732e6/src/main/java/scala/compat/java8/runtime/LambdaDeserializer.scala
