simonbronkandClaude Opus 5.5 bf0806ecd6 fix(agc): retire an unwritten native multisample depth surface on guest access
A guest read over the depth or HTILE range of a native multisample depth
surface threw even when the host had not written the surface since its
import. Its samples are then still the clear value the import took from
the guest HTILE, so the guest bytes already describe it. Retire such a
surface and its guards instead, and keep the refusal for a surface the
host wrote: draws with depth or stencil writes, depth/stencil copies and
storage write-back.

Onimusha: Way of the Sword (PPSA27836) imports a 4-sample D32 target,
draws into it once with depth tests only and no color target, then reads
the memory back as a structured buffer in a compute dispatch.

Unblocks PPSA27836.
