view.h uses std::exchange but <utility> not included

impl/winmd_reader/view.h uses std::exchange but <utility> has not been explicitly included. It fails to build on GCC 12 / libstdc++ with error: 'exchange' is not a member of 'std'.

Feel free to contribute a fix, although this library doesn't get updated often so it may not be worth the effort when the workaround is pretty simple.

I agree, and it's already handled in cppwinrt.
