  [Backport branch-8-6] size msClipPolygonRect buffer for 3 emitted points per edge (#7588)

* size msClipPolygonRect buffer for 3 emitted points per edge

* add msautotest case for polygon clipping at the rect corners

Two inline rings whose edges cut across the corners of the clip rectangle,
so a single edge emits three points and the clipped rings come out at 14 and
16 points from 6 and 7. Against the previous 2*numpoints allocation this
aborts under ASAN in msDrawShape().
