Currently, CPU backends in the PSTL are created by defining functions in the __par_backend namespace. Then, the PSTL includes the CPU backend that gets configured via CMake and gets those definitions. This prevents CPU backends from easily co-existing and is a bit confusing. To solve this problem, this patch introduces the notion of __cpu_traits, which is a cheap encapsulation of the basis operations required to implement a CPU-based PSTL. Different backends can now define their own tag and coexist, and the CPU-based PSTL will simply use __cpu_traits to dispatch to the right implementation of e.g. __for_each. Note that this patch doesn't change the actual implementation of the backends in any way, it only modifies how that implementation is accessed to implement PSTL algorithms. This patch is a step towards #88131.
