Remove unnecessary core library neverallow rules

The rules that restricted access to core library targets are no longer
required as they have been replaced with visibility rules. The
visibility rules are safer because they check all dependencies whereas
the neverallow rules that have been removed only checked dependencies
in the libs property and so missed dependencies in static_libs and
java_libs properties.
