Implements the `currentCSSZoom` readonly attribute on the Element
interface as
[spec](https://drafts.csswg.org/cssom-view/#dom-element-currentcsszoom).
- Adds a new layout query (`CurrentCSSZoomQuery`) that traverses from
the target element up through its ancestors
- Accumulates the product of all `zoom` CSS property values to compute
the effective zoom
- Returns 1.0 for elements that are not being rendered (display: none or
no layout data)
Testing: Updated WPT (removed 4 FAIL expectations from
`idlharness.html.ini`). Behavior tests in Element-currentCSSZoom.html
remain as expected FAIL because the underlying CSS `zoom` property
implementation in Servo does not yet apply zoom values to layout (the
zoom property is parsed but computed values remain 1.0).

Callers now call `set_attribute` directly, to avoid the trusted types
machinery, as well as skip validation. That's not required by spec as
well.

This is an implementation for `scrollIntoView`. For now, it is called
when a certain element gains focus.

Also implements a conversion for `TrustedHTMLOrNullIsEmptyString`
to `TrustedHTMLOrString` to avoid introducing a separate
`get_trusted_script_compliant_string` for the new type.
