[highlights] Paint custom highlight backgrounds over replaced elements
Build on the replaced-element tracking added by the parent CL to
actually paint custom ::highlight() background tints over replaced
elements such as <img>.
- ReplacedPainter::PaintCustomHighlights() fills the area the replaced
content occupies (the content box, or the replaced object's rect when
it overflows the content box) with the active custom-highlight
backgrounds, in the foreground phase, after the replaced content and
below the existing ::selection tint in the highlight overlay order.
- Stacked highlights resolve background-color: currentColor against
the previous highlight layer, mirroring HighlightOverlay::
ComputeParts() for text, so a higher-priority layer's currentColor
reflects the lower layer's resolved color rather than the host
element's color.
- The cached drawing is consulted before resolving any colors, so
cache hits skip the stacking sort and per-layer color resolution.
