JJenkxandClaude Opus 5.5 2ff14f34e3 fix(agc): emulate two-sample DB_ALPHA_TO_MASK 0xe701 dithered alpha-to-coverage
Bugsnax (PPSA01503) draws with DB_ALPHA_TO_MASK 0xe701 (quad offsets
3, 1, 2, 3 without OFFSET_ROUND) on a two-sample target and stopped on
the refusal of every dither but the eight-sample 0x18701. The pixel
shader now applies an eight-level per-quad table for it, measured
natively on gfx1032, and the request's dither byte selects that table
(serialization version 47). It is accepted only for two matched raster
and DB_EQAA samples, the two measured location pairs and FP16_ABGR or
32_ABGR exports.
