Move dagger modules into shell library for reuse

- Certain system ui implementations which use the shell don't depend on
  SystemUI-core, which means that the dagger modules for providing the
  core Shell components need to be copied (which makes it more cumbersome
  to make changes). Instead, move these modules back into the shell lib
  for any SysUI app to reference.
