DDC's codegen test copies those files to a local "gen" directory so that it can do stuff like splitting out the multitests before it compiles them to JS. I left all of that alone, so the rest of DDC's test infrastructure is unchanged. The very first step that builds the "gen" directory just copies from sdk/tests/..._strong/... instead and the rest is good to go. I did not move not_yet_strong_tests.dart somewhere more accessible yet because I'm not sure if kernel needs it or where it should go. I did not create any status files because DDC doesn't need them and there are no test suites for the new directories for the other platforms.
