D3D12 previously assumed native point-list + geometry-shader expansion; that path can drop or rasterize points incorrectly (invisible missile trails). Default to the shared triangle-strip VS expansion path with an init-time CVar override.
Vulkan: default vulkan_force_expand_point_sprites_in_vs to true for the same behavior on non-D3D12 hosts.
