Revert^2 "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.

This change relands https://r.android.com/3035972. Implementation
changes from the original change:
- "all_apex_contributions" is added as a dependecy to the implementation
  library modules where the parent sdk_library module has a prebuilt
  equivalent. This allows the source apex variant to be hidden from make
  when the prebuilt is active.

Test: patch in internal main, lunch barbet-ap2a-userdebug && m nothing
Test: m nothing --no-skip-soong-tests
