Embed NOTICE output as an APEX asset.

Instead of outputting an aggregated NOTICE file as an intermediate build
resource to allow Make to include it in the final system-wide NOTICE,
process and embed it as an asset in the final APEX. This allows us to
update the NOTICE contents automatically when an APEX is updated.
