LibWeb/CSS: Mark list-valued properties

Browse Source 
Typed-OM requires us to have a generic way of asking "does property X
accept a list or a single value?" so this exists mainly for that.
Coordinating lists are annotated too - I'm not clear on exactly what
will be needed for those, but giving them a unique value now at the
worst will make them easier to find later.

### `multiplicity`
The three possible values are `"single"`, `"list"`, and `"coordinating-list"`.
Most properties represent a single "thing", possibly made of multiple parts. For example, `border` takes a color, style
and thickness, but it's still a single border. Others are a list: `background` takes multiple layers, separated by
commas; `counter-increment` doesn't have commas but also is a list of counters that are incremented.
Lists can also be [coordinating list properties](https://drafts.csswg.org/css-values-4/#linked-properties), in which
case they are marked as `coordinating-list` instead of `list`.
