type_traits: Deprecation warnings with clang 15

[cs96and]

I am getting a lot of deprecation warnings when using Boost with Clang 15. E.g.

boost/type_traits/has_nothrow_constructor.hpp:27:84: warning: builtin __has_nothrow_constructor is deprecated; use __is_nothrow_constructible instead [-Wdeprecated-builtins]

boost/type_traits/has_nothrow_assign.hpp:65:7: warning: builtin __has_nothrow_assign is deprecated; use __is_nothrow_assignable instead [-Wdeprecated-builtins]

boost/type_traits/has_nothrow_copy.hpp:36:89: warning: builtin __has_nothrow_copy is deprecated; use __is_nothrow_constructible instead [-Wdeprecated-builtins]

boost/type_traits/has_trivial_constructor.hpp:41:69: warning: builtin __has_trivial_constructor is deprecated; use __is_trivially_constructible instead [-Wdeprecated-builtins]

boost/type_traits/has_trivial_destructor.hpp:30:86: warning: builtin __has_trivial_destructor is deprecated; use __is_trivially_destructible instead [-Wdeprecated-builtins]

boost/type_traits/has_trivial_assign.hpp:29:7: warning: builtin __has_trivial_assign is deprecated; use __is_trivially_assignable instead [-Wdeprecated-builtins]

boost/type_traits/has_trivial_copy.hpp:34:4: warning: builtin __has_trivial_copy is deprecated; use __is_trivially_copyable instead [-Wdeprecated-builtins]

The errors are all in boost/type_traits/intrinsics.hpp. This is with boost 1.72.0, however I took a look at the 1.80.0 source code and it doesn't look like it has been fixed.

See the Clang 15 documentation for more details...

@cs96and It should be fixed in the upcoming 1.81 release via a1d0b20
