Vscode-cpptools: Allow Modifying Variable with Mouse Hover Preview while Debugging.

[skl131313]

Currently when debugging, you can hover over a variable to see its value. It would be more convenient if the value could be modified from this preview window. Rather than having to search through the list of variables.

@sprinkle131313 You should be able to add it to watch and modify it instead of searching through variables

This refers to the popup in the editor though, just like VS DataTips which offer even more functionality like adding expressions and pinning. So I guess this could be the "implement DataTips like in VS" tracking ticket.
