Per https://drafts.fxtf.org/motion/#path-distance, we follow these rules when `offset-path` references to a SVG shape: 1. Offset paths (including references to SVG Paths) are closed loops only if the final command in the path list is a closepath command ("z" or "Z"), otherwise they are unclosed intervals. 2. References to SVG circles, ellipses, images, polygons and rects are closed loops. 3. References to SVG lines and polylines are unclosed intervals. Also, rename `mIsClosedIntervals` as `mIsClosedLoop` to be consistent. Differential Revision: https://phabricator.services.mozilla.com/D184430
