Align triangle winding of triangles in default AS geometry

Align triangle winding of triangles in default AS geometry

Change triangle winding of deatult AS geometry so the two triangles
would match in winding. This makes the triangles share an edge, forming
waterthight geometry.

This fixes tests that were casting the rays in the direction of the edge,
like dEQP-VK.binding_model.descriptor_buffer.single.graphics*.
