script: Create CSSStyleOwner::Null for getComputedStyle (#36272)

This new `CSSStyleOwner` variant is used when the pseudo-element
argument fails to parse properly or is for some unknown or unsupported
pseudo-element.

Testing: There are tests for this change. Various tests start to pass
and some start to
fail. New failures are due to partial or fully missing support for
pseudo-elements such
as:
 - `::selection`
 - `::first-letter` and `::first-line`
 - `::marker`
