Modernize View Properties window
Like D12571, but for the View Properties Window. Also did a little bit of re-organization. This allows us to use a QFormLayout as the top-level layout and simplify the code a lot, including no longer using the now-unnecessary paradigm of putting a layout inside a QWidget, and ending the use of QGridLayout to make a fake and more complicated form-style layout.
Depends on D13749
Window still resizes properly when the Additional Information content is shown or hidden.
