Fix hit testing under multicol under perspective

The perspective transform node applies to contents so it's in
ContentsProperties() instead of LocalBorderBoxProperties().
Previously we used LocalBorderBoxProperties() to match container
and child fragment data, matching wrong container fragment data.

Also fix CollectFragments() when root_fragment_arg is specified
(when root_layer has transform or perspective). Previously
CollectFragments() mapped local fragment geometries into wrong
container fragment space (which was always the first root
fragment).
