Implement shadow dom slots (#35013)
* Implement slot-related algorithms

Signed-off-by: Simon Wülker <simon.wuelker@arcor.de>

* Hook up slot elements to DOM creation logic

* Assign slots when a slottable's slot attribute changes

* Properly compute slot name

* Update <slot> name when name attribute changes

* Implement fast path for Node::assign_slottables_for_a_tree

assign_slottables_for_a_tree traverses all descendants of the node
and is potentially very expensive. If the node is not a shadow root
then assigning slottables to it won't have any effect, so we
take a fast path out.

* Move slottable data into ElementRareData

This shrinks all element descendants back to their
original size.
