Use new libcore filegroup variable

This change switches frameworks/base/ targets to a generic "interface"
libcore filegroup variable, core_public_api_files, rather than having
it know about Core Library internal filegroups. It is not perfect
because the command line tools need to know to exclude certain packages,
but it is a step in the right direction.
