AK: Delete bad pointer assignment operators and constructors.
We shouldn't allow constructing e.g an OwnPtr from a RefPtr, and similar conversions. Instead just delete those functions so the compiler whines loudly if you try to use them. This patch also deletes constructing OwnPtr from a WeakPtr, even though that *may* be a valid thing to do, it's sufficiently weird that we can make the client jump through some hoops if he really wants it. :^)
