Makefile.target: add (clean-/build-)guest-tests targets

Now all the build infrastructure is in place we can build tests for
each guest that we support. That support mainly depends on having
cross compilers installed or docker setup. To keep all the logic for
that together we put the rules in tests/tcg/Makefile.include and
include it from the main Makefile.target.
