[libc++] Fix PR22606 - Leak pthread_key with static storage duration to ensure all of thread-local destructors are called.
See https://llvm.org/bugs/show_bug.cgi?id=22606 for more discussion.
Most of the changes in this patch are file reorganization to help ensure assumptions about how __thread_specific_pointer is used hold. The assumptions are:
* `__thread_specific_ptr<Tp>` is only created with a `__thread_struct` pointer.
* `__thread_specific_ptr<Tp>` can only be constructed inside the `__thread_local_data()` function.
I'll remove the comments before committing. They are there for clarity during review.
