Improve error message for passing vector<bool> as array_view

[oldnewthing]

std::vector<bool> is not a conformant array of bool. Passing it to array_view<bool> results in a long incomprehensible error message because there is no data() member. Add specializations for "constructing array_view<bool> from std::vector<bool>" so we can provide a clearer error message.

Old error message:

New error message;

error C2338: Cannot use std::vector<bool> as an array_view. Consider std::array or std::unique_ptr<bool[]>.
note: see reference to function template instantiation 'winrt::array_view<bool>::array_view<void>(std::vector<bool,std::allocator<_Ty>> &) noexcept' being compiled
        with
        [
            _Ty=bool
        ]
note: see reference to function template instantiation 'winrt::array_view<bool>::array_view<void>(std::vector<bool,std::allocator<_Ty>> &) noexcept' being compiled

            _Ty=bool
        ]

Note that we specialize only in the case of array_view<bool>. That way, if you pass a std::vector<bool> to a function expecting array_view<hstring> (say), you don't get an error message telling you to use something (std::array<bool>) that won't work. (Should we have a separate error message for type mismatch? Maybe this is good enough for now.)

Fixes #568
