Andreas Kling 8caca053a3 LibWeb: Avoid IntersectionObserver registration lookups 
IntersectionObserver updates already iterate over each observer and its
observation targets. We then looked the same target and observer pair up
again through Element's registered observer list just to read and write
previousThresholdIndex and previousIsIntersecting.

Store that mutable state with the observer-side observation target
instead. The element-side list now only keeps strong observer
references for lifetime management and unobserve/disconnect.

This deviates from the spec's storage model, so document the difference
next to the preserved spec comments.
