This change mechanically copies runtime/tests/vm/dart -> runtime/tests/vm/dart_2 in preparation for the migration of runtime/tests/vm/dart to NNBD. Corresponding statuses in vm.status are duplicated. Added vm_nnbd builder tag for NNBD bots. vm/dart/* tests are allowed to run only on vm_nnbd builders. vm/dart_2/* tests are allowed to run only on non-vm_nnbd builders.
