Remove compilation actions from java sdk library

This change modifies the build actions of java_sdk_library module type
so that it does not perform any compilation actions (i.e. does not
create the top level java_sdk_library jar file). Instead, it delegates
the build actions the top level jar file was performing to the
dynamically created ".impl"-suffixed java library module. The build
actions that are delegated to the impl library module include hiddenapi
processing, dexing, and dexpreopt.
