QMetaType: use sized delete to deallocate a value

Browse Source 
When destroying a value created by QMetaType::create(), pass the size
to operator delete. This allows allocators to potentially optimize the
deallocation.

The size passed is always the one used during allocation, iface->size.

As a drive-by, make the operator() function const.
