Remove more _Atomic keywords from public headers

Browse source 
It's been thirteen years and C++ still hasn't implemented this wonderful
simple builtin keyword. In C++23 a solution was provided for making this
work in C++ which is libcxx's stdatomic.h. Including that header schleps
in literally 253 unique header files!! Many of the header files it needs
are libc header files like pthread.h where we need to have the _Atomic()
keyword, but since <atomic> depends on pthreads we can't have it include
the <stdatomic.h> header that defines _Atomic for C++ users, and instead
we simply make the type non-atomic, hoping and praying only C code shall
use those internal data structures. This just shows how STL clowns can't
be trusted to define the innermost primitives of a language. They should
instead be focusing on being the best at algorithms and data structures.
