This adds TShadowRoot to the `dom` module.
Right now it barely adds uses of it, but this is a prerequisite to fix a bunch
of Shadow DOM bugs and separate it from the XBL mess.
Unconditionally derive ToComputedValue as Clone for non-generic types
We assume that types such as `<Self as ToComputedValue>::ToComputedValue == Self`
just construct a new value that is just a clone of the original one without any
additional code.

#20174 removed the option and unwrap
I removed the useless option and the need for unwrap from default_config_dir

Support zero rowspans
This makes rowspan=0 work by storing notes on which group of rows we're in
for tables containing both rowgroups and rows, and using that to respan
cells with overlarge or zero rowspans.
This also gets rid of the largest_leftover_incoming_size business, because
now spans will always be correct and we'll never have any left over.

Rowspan support for tables
fixes#20092
This just contains the first steps.
We apply a naive algorithm: Spanning cells apply a pressure equal to `block_size / rowspan` on each row they are in. We move table row block size computation into the tables, and make it two pass. In the first pass we compute the sizes of each row, and in the
second pass we assign them, adding them up for any involved cells.
This is missing:
- [x] Accounting for border sizes
- [x] Applying pressure to rows that are not the row containing the cell
- [ ] Reducing pressure on future rows if the current row is able to accomodate more of the cell
- [x] For tables containing both rows and rowgroups, reset the rowspan info when we hit a rowgroup
- [x] Correctly handle overflowing rowspans

style: Only expose longhands to rust via iterators.
The key here is that we only filter longhands if the shorthand is accessible to
content and vice-versa. This prevents the bug that prevented me to land this
patch before, which was us not expanding properly chrome-only shorthands.
