chrg6 e8b4d29f91 Give mesh output components outside the program's output map Maxwell's default of (0, 0, 0, 1). ...

A mesh program's header lists the components of each output vector it has; the fragment stage may read the others.
The native mesh entry function never wrote them, so they read as whatever the output held, and the fallback's vertex
stage wrote 0 for all of them, w included. Maxwell gives an unwritten component (0, 0, 0, 1), as the pipeline code
already pads a missing vertex output. Both paths now write that default: MeshSpirv.cs after copying each vertex's lines,
mesh_fb.c meshfb_vs with w as the bits of 1.0f whatever the type.

Checked: all 520 task and mesh programs of an installed shader cache translate and pass spirv-val (vulkan1.3); 500
mesh modules gained about 730 bytes each on average, so many of the game's mesh programs have partly listed vectors.
--probe-meshfb passes (fallback pictures equal the mesh pipeline's), and its module part converts all 520 new
translations with 0 failures, all 1,020 modules pass spirv-val and their compute pipelines build.
