script: Use an implemented pseudo-element to fortype=color ::color-swatch (#37427)
Implement internal pseudo element, which would be resolved as a
"Implemented Pseudo Element" within style computation. This is an
concrete element that would has a primary style after the style
computation, but could match and style resolved like an pseudo element.
Therefore, it would have a different behavior compared to how does
`pseudo`s that `ServoLayoutNode` had. Where they would not have a
concrete element behind it. Note that, due to the nature of these pseudo
elements residing inside a UA widget, these pseudo elements would
therefore not be accessible in JavaScript by default.

This kind of element is required in order to implement the [form control
pseudo element](https://drafts.csswg.org/css-forms-1/#pseudo-elements)
like `::placeholder`, `::color-swatch`, `::field-text`, etc.
 
See [this docs](https://hackmd.io/@ChaKweTiau/BJ3zRdLQlg) for more
details of the implementation.

Then, the implemented pseudo element is utilized to implement style
matching for input `type=text`.

Servo's side of: https://github.com/servo/stylo/pull/212

Testing: No WPT regression.
