Add merged txt filegroups that depend on the exportable non-updatable txt files

Currently, ther merged txt filegroups are dist'ed as api/*-current.txt
and api/*-removed.txt files during droid dist build.

This change adds additional merged txt filegroup modules
that depend on the non-updatable exportable txt files instead of
the checked in non-updatable txt files (under frameworks/base/core).

These added modules will be dist'ed in droid build, instead of the
currently existing merged txt filegroups.

Test: m nothing && inspect ninja output
