Don't generate potentially unsupported vertex formats to ignore W

Browse Source 
* When using VS In we want to ignore the W component, but that already happens
  explicitly for vulkan/GL in the shader. Mirror that same solution to D3D
  instead of trying to force a 3-component format which may not be supported
  (e.g. on AMD R16G16B16_*)
