fix(rendering): enable backface culling for one-sided M2 materials (#57)

Browse source 
All M2 pipelines used VK_CULL_MODE_NONE, so back-facing polygons always
rendered.  On NPCs whose torso meshes are single-layer geometry this
made the interior cavity visible through the back.

Create backface-culled pipeline variants (VK_CULL_MODE_BACK_BIT) and
select them at draw time unless the material has the TwoSided flag
(0x04).  Foliage/ground-detail forceCutout batches and the shadow
pipeline keep VK_CULL_MODE_NONE since those cards are inherently
two-sided.
