[Qt] [WK2] Implement popup menus in QDesktopWebView using QComboBox

Less general than the bug 62191, but I see it as a starting point. With this patch QDesktopWebView will have a working combobox.

Then we can figure out the best way to allow this to be customized by API users (or decide whether we want that).

avoid -> avoids

We need a comment here, explaining that we need to hang on to the pointer since this is a 2-step process on Qt.

> Source/WebKit2/UIProcess/qt/WebPopupMenuProxyQtDesktop.cpp:48
> +    QWidget* parentWidget = m_webViewItem->canvas();
> +    comboBox->setParent(parentWidget);

No need for the parentWidget variable here.

> Source/WebKit2/UIProcess/qt/WebPopupMenuProxyQtDesktop.cpp:95
> +    for (int i = 0; i < items.size(); ++i) {

int i -> size_t i

> Source/WebKit2/UIProcess/qt/WebPopupMenuProxyQtDesktop.h:44
> +    Q_DISABLE_COPY(WebPopupMenuProxyQtDesktop)

Is this necessary?

> Source/WebKit2/UIProcess/qt/WebPopupMenuProxyQtDesktop.h:58
> +    void selectIndex(int index);

I'd call this "setSelectedIndex(int)"

> Source/WebKit2/UIProcess/qt/WebPopupMenuProxyQtDesktop.h:69
> +    int32_t m_selectedIndex;
> +    QSGItem* m_webViewItem;

Nit: Reverse the order of these two members, since QSGItem* is bigger than int32_t on 64-bit.

Not strictly. I took it off since it seems to cause more noise than benefit.

All the other comments were addressed by the new attached patch.

Looks good, let's start with this!
r=me with this tiny (perhaps personal) style nit:

> Source/WebKit2/UIProcess/qt/WebPopupMenuProxyQtDesktop.cpp:87
> +    Q_ASSERT(comboBox);

Q_ASSERT -> ASSERT

> Source/WebKit2/UIProcess/qt/WebPopupMenuProxyQtDesktop.cpp:92
> +    Q_ASSERT(model);

Ditto.
