Remove the `-lower-global-dtors-via-cxa-atexit` escape hatch introduced in D121736 [1], which switched the default lowering of global destructors on MachO to use `__cxa_atexit()` to avoid emitting deprecated `__mod_term_func` sections. I added this flag as an escape hatch in case the switch causes any problems. We didn't discover any problems so now we can remove it.
