milescovielloandClaude Opus 5.5 cd5fc9e838 feat(agc): draw tessellation followed by an NGG geometry stage
Crimson Desert (PPSA25286) draws with VGT_SHADER_STAGES_EN 0x60212d:
local, hull, domain and NGG geometry stages, the hull halves merged in one
registered type-3 program, the domain and geometry halves in one type-2
program. The domain half runs as the tessellation evaluation stage and
captures each vertex's ESGS item, and a mesh shader runs the geometry half
on the captured items.

Registered type-3 merged hulls come from #6679; this adds 16-bit LDS
reads and writes in tessellation stages, which Crimson Desert's merged
hull uses.
