SandstromPLandClaude Opus 5.5 474ec771bf fix(agc): accept a min or max reduction sampler with anisotropic filtering
A guest S# with FILTER_MODE min or max and an anisotropic XY filter
threw "combines a min or max reduction with anisotropic filtering",
which stops High on Life (PPSA15388) in its home base. It now decodes
to a Vulkan sampler with both anisotropy and the reduction mode, as a
weighted-average anisotropic S# already does. RADV programs the same
S# for such a Vulkan sampler.

Tamalero's gfx1030 measurement on #5156 covers a sample without
derivatives through a 2x anisotropic S# over a single-level texture:
min or max with anisotropic bilinear returns the bilinear minimum or
maximum, and min with anisotropic point the point result. The
execution test checks the bilinear case on the host GPU; the debt
entry records what is not measured.
