Andreas Kling ad7e6878fe LibWeb: Allocate CSS::ComputedValues objects on the heap
This makes them cheap to move around, since we can store them in a
NonnullOwnPtr instead of memcopying 2584(!) bytes.

Drastically reduces the chance of stack overflow while building the
layout tree for deeply nested DOMs (since tree building was putting
these things on the stack).

This change also exposed a completely unnecessary ComputedValues deep
copy in block layout.
