Support locals and inspection of QObject and object variables in QML debugger

It currently seems to be able to only show the value of a variable itself, not the contents of object type or QObject. For example:

var f = {"key": 33}
 

Hovering over f only shows "

" as the value and it cannot be expanded either. Same for QObject types, for example:

var f = Qt.platform

Also Locals view does not list local variables.

These all work in Qt Creator, so they should be doable and it would be nice VS had feature parity with QML debugging.
