Decouple java_lite_proto_library from java_proto_library

Remove call to java_proto_library_impl from java_proto_library.

Remove hasattr from java_proto_library_impl, which handled java_lite_proto_library.

Code reuse in this case made little sense, and it incurrent more maintenance cost than benefit.
