[MODULARIZE=instance] Mark MINIMAL_RUNTIME as not supported

Also disable a bunch of unsupported tests.

Now we can run the entire core test in MODULARIZE=instance mode!  I'm
adding a new test running here, which we might not want to keep around
forever, but its very useful while working on ESM integration.
