[csswg-drafts] [css-nesting-1] [selectors-4] Figure out the specificity of nesting with pseudos and non-pseudos (#13108)

emilio has just created a new issue for https://github.com/w3c/csswg-drafts:

== [css-nesting-1] [selectors-4] Figure out the specificity of nesting with pseudos and non-pseudos ==
In #9702, we're defining that something like this works and selects the pseudo-element:

```css
.foo, ::before, ::after {
  &:hover { color: red }
}
```

However, it's not currently defined what the specificity of a pseudo-element is.

This is usually not observable, but will become observable now, so we also need to define that.

See #9600 for a similar bug where we defined that those are zero
