[resize-observer] m_target could be null in
ResizeObservation::computeObservedSizes

Reviewed by Simon Fraser.
Crash reports indicate that when ResizeObservation::computeObservedSizes is
called,
it's possible for m_target to be nullptr, indicating the Element was destroyed
before the method is called. So far I've not been able to reproduce this nor
figure out a plausible explanation, so this patch speculatively fixes it by
adding a null check, plus turning the WeakPtr into RefPtr before using it.
