Treat java libraries in classpath fragments as directly in apex

Coverage is applied to java libraries that are directly in an apex.
Mark java libraries that are in an apex through a bootclasspath_fragment
or a systemserverclasspath_fragment as directly in the apex by
implementing CopyDirectlyInAnyApexTag on the dependency tags used for
their contents.
