win32: Fix lifetime tracking of create_similar_image()
As we return the child image to the user and so perform the reference
tracking on it and not the parent win32 display surface, we need to add
a call to destroy the parent from the image surface. This of course
complicates the normal scenario of destroying the parent first, and so
in that case we need to unhook the image->parent before freeing the
surface->image.
