Refactor Dialog and Popup to remove jquery

[jernestmyers]

Works to resolve the second wdk-client task from #899: Overlays/Popup: used only in Dialog, but Dialog is used widely

It's worth noting that the draggable prop passed to Dialog was being ignored. Whether or not draggable was passed into Dialog and thus down to Popup, it was always rendered as draggable. With these changes, I'm listening to the draggable prop and only rendering a draggable Dialog when it's explicitly passed in.

I think this looks great. However, I think we need to make the component draggable by default. There are some places where we definitely want the dialog to be draggable, even though we don't specify it. For example, the step details dialog in the strategy panel.

If you have the time and energy, you could find all of the places where we use the Dialog component and we can determine if each one should be draggable. Otherwise, let's just make it the default behavior.

I opted for the simpler solution of defaulting to true. That's essentially how it was working before, though now I suppose we'll needlessly be passing draggable=true to some components.
