Add an exported flag in manifest

With b/150232615, we will need an explicit value set for the exported
flag when intent filters are present, as the default behavior is
changing for future versions. This change adds the value reflecting the
previous default to the manifest.

These changes were made using an automated tool, the xml file may be
reformatted slightly creating a larger diff. The only "real" change is
the addition of "android:exported" to activities, services, and
receivers that have one or more intent-filters.
