[boost] [config] std::uncaught_exceptions

Hello all,

std::uncaught_exception (singular) is deprecated in C++17 and will be
removed in C++20. std::std::uncaught_exceptions (plural) should be
used instead.

Will Boost.Config have a macro to detect if std::uncaught_exceptions
is supported or not by the current compiler?

(For example, Boost.Contract implementation uses
std::uncaught_exception and it will need to use
std::uncaught_exceptions on C++20 compilers instead.)

Thanks.
