Auto merge of #18844 - jryans:stylo-visited-reparent-cascade, r=emilio

Browse source 
Limit visited cascade for reparenting

The specialized cascade flow in `stylist::compute_style_with_inputs` (used with
reparenting) currently computes all properties for visited styles, but we only
need visited-dependent properties.

This adds the cascade flag to reduce the work to visited-dependent properties
only, like we do for the regular cascade flow.
