Avoid crash above CFWL_ListItem::GetText()
The issue at hand is caused by a raw pointer rather than a
retained pointer in InheritedData::m_pFontFamily. But the
larger issue is that it's bad to Get() raw pointers from
these, especially when its so cheap to pass them by const
reference.
One reason to Get() a raw pointer is to aid in down-casts, so
add a helper to CFX_RetainPtr to give us downcasted retained
pointers.
