Modernize the test specs of various outdated tests

These generated test were in an earlier format for test_generator,
and were not re-generated when running generate_test.sh

This CL converts the test spec to a modern test spec. Removed manually
written includes in TestGenerated as well.

Also removed test harness for those outdated tests since it is no
longer used.
