Give access to the reverse geocoder when app is run on platforms not supporting touch input

[mikewilburn]

When the app is run on desktops not supporting touch screen input, allow the reverse geocoding functionality to be prompted with a map click.

I recently ran into this on UWP and WPF when testing the app on Parallels for Mac. It would be nice for the app design to provide a consistent set of functionality regardless of whether touch input is supported.

This is a nice-to-have and not a must-have piece of functionality.
