script: Eliminate `PseudoElementType` (#36146)

Servo has a `PseudoElementType` which more or less duplicate's Stylo's
`PseudoElement` with the addition of a non-pseudo element variant. This
type needs to be converted into `PseudoElement` anyway when asking for
the style of an element from Stylo, so eliminate Servo's version and
simply use `Option<PseudoElement>` with the `None` variant meaning the
non-pseudo.

This is preparation for adding support for the `::marker` pseudo
element.
