remove CD_POLYINDEX customdata layer:

reported as [#29376] BMESH_TODO: remove tessface CD_ORIGINDEX layer

for a single mesh there could be 3 origindex mappings stored, one on the polygons and 2 on the tessfaces.
(CD_POLYINDEX and CD_ORIGINDEX).

as Andrew suggests, now tessfaces (which are really a cache of polygons), using origindex to point to polygons on
the same derived mesh, and polygons only store the original index values.
