Initialize TSD on macOS even without Swift runtime (#1695)

Without this, you get some really fun to debug segfaults at runtime
because (among other things I assume) CFRunLoopGetCurrent queries TSD
to avoid doing the heavier _CFRunLoopGet0 (which then sets the TSD to
avoid later work). But if we don't initialize the TSD machinery, the
_CFGetTSD function returns garbage and we never get a valid CFRunLoopRef
