[libc++] Mark __call_once_proxy as hidden and internal

Browse Source 
We effectively never want to export that function, which is an
implementation detail of libc++. This was previously tried in
603715c66b6b and then reverted in 8335dd314f36 because it caused
linker warnings. These linker warnings should go away now that we
use internal_linkage instead of always_inline to implement per-TU
insulation.
