* Inquiry: SHAPES reports closed-shape geometry facts

`shapes` is a read-only command that reports, for every closed shape in the
current space (closed polylines, circles, full ellipses, closed splines),
its perimeter, area, centroid, winding, first self-intersection and
coincident vertices, exact with arcs and bulges. It filters and pages like
`entities` and counts other matches under `skipped` with the reason.

`Polyline::centroid` and `polygon_centroid` give the area centroid.

Fixes #1436.
