  [libc++] Fix __threading_support when used with C11 threading (#66780)

Since we are defining these typedefs inside namespace std, we need to
refer to ::once_flag (the C Standard Library version). Otherwise
'once_flag' refers to 'std::once_flag', and that's not something we can
pass to the C Standard Library '::call_once()' function later on.
