DirectShow: Fix uninitialized memory read in DirectShowMediaTypeEnum::Next()
Newly allocated memory was passed to DirectShowMediaType::copy(), which calls
DirectShowMediaType::clear() on the target, which crashes when trying to
release a COM pointer.
Split out a DirectShowMediaType::copyToUninitialized() helper function
which does not call clear() for this purpose.
Task-number: QTBUG-59515
