Dipshet 2c7ee7ea68 Fix cull the sun-flare's spurious second billboard (flare "square") ...

The sun lens-flare draw (VS ADF9AFC4C10921B9 emits two billboards:
V0-V3 = the visible glow quad, V4-V7 = a malformed quad that mis-renders
in the emulator as a faint  bright rectangle in the sky (the "square").

Cull it in the vertex shader using the translator's existing kill-vertex
mechanism: in CompleteVertexOrDomainShader, for this ucode hash
(plain host VS only), vertices with SV_VertexID >= ac6_flare_drop_index_min
(default 4) get a NaN output position, so the rasterizer discards the primitive.
The real glow (V0-V3) is untouched.

cvars: ac6_flare_drop_quad2 (bool, default true), ac6_flare_drop_index_min
(int32, default 4). Baked at shader translation.
