Propagate inherited properties into slotted elements on recalc.
When we reach a <slot> element during recalc, we need to trigger recalc
of elements distributed to that slot for inheritance. This is similar
to what is done for InsertionPoint. I have however not found a case
where we need a bigger cannon than LocalStyleChange on the distributed
elements.
Made a few override methods final, expecting no inheritance of
HTMLSlotElement.
