libstdc++: Add noexcept to some std::promise shared state internals
Making the state ready for a std::promise<void> only needs to move a
unique_ptr, which cannot throw. Make its call operator noexcept.
Similarly, making the state ready by storing an exception_ptr also can't
throw, so make that call operator noexcept too.
libstdc++-v3/ChangeLog:
* include/std/future (_State_baseV2::_Setter<R, void>): Add
noexcept to call operator.
(_State_baseV2::_Setter<R, __exception_ptr_tag>): Likewise.
