Nyall Dawson eea155d6e2 Fix crash when attempting to render multipolygon with missing exterior ring ...

This commit fixes a possible crash when the vector layer renderer
attempts to render a multipolygon containing a polygon without
an exterior ring.

The underlying cause of the creation of this invalid geometry is deeper,
but this commit hardens the renderer and makes it more robust for
handling bad geometries.

Fixes #17365
