[Makefile] Move tags generation to standalone Makefile

After deprecating the top-file Makefile, "make tags" cannot easily be
used any more. Moving the tags-related rules out to a separate Makefile
allows to continue using it using either "make -f tools/Makefile.tags
tags", or including it in your own Makefile.
