PR72792 detect allocator pointer types without invalid rebinding
PR libstdc++/72792
* include/bits/alloc_traits.h (__allocator_traits_base::__diff_type)
(__allocator_traits_base::__size_type): Remove.
(allocator_traits::_Ptr): New class template to detect const and void
pointer types without instantiating pointer_traits::rebind
unnecessarily.
(allocator_traits::_Diff): Likewise for detecting difference_type.
(allocator_traits::_Size): New class template to detect size_type
without instantiating make_unsigned unnecessarily.
* include/bits/ptr_traits.h (pointer_traits::element_type): Use
__detected_or_t instead of __detected_or_t_.
* include/std/type_traits (__detected_or_t_): Remove.
* testsuite/20_util/allocator_traits/members/pointers.cc: New test.
