Use 'globalThis' instead of 'this' when trying to attach a debugger to the current global to avoid subtle footguns with the varied definitions of 'this'. The debugger interface needs a true GlobalObject so this is much clearer. In particular, this is a problem in test_nativewrappers.js when the test runs in strict mode since the 'this' in the test function is no long implicitly the global.
