servo: Merge #20602 - Don't make logical properties animatable (from hiikezoe:dont-make-logical-properties-animatable); r=emilio

|animation_type| was renamed in 94fb839fdde, but the commit missed renaming
one place.  It means that some of logical properties might have been
accidentally animatable.  Logical properties should be animatable but we
haven't yet implemented the proper Animate trait for logical properties.
