XairRrR 6849eeaec0 perf(agc): drop the guest byte snapshot of a large cached texture the write tracker covers ...

Every snapshot texture in the sampled texture cache kept a host copy of
its guest bytes, used only when the write tracker reports the surface
written, to tell a rewrite of the same bytes from a change. The cache
budget counts the GPU allocation alone, so the host copies grew with it:
PPSA05684 held 2.7 GB of them in its first level.

A snapshot larger than 256 KiB is released after the upload when the
write tracker (a write generation or an untracked key) can prove the
surface unchanged. A tracked write to such a surface re-uploads it
instead of comparing bytes; smaller snapshots, and surfaces the tracker
cannot vouch for, keep their copy as before.

agc_driver_large_tracked_snapshot samples a 1 MiB surface, committed
and partially resident: an unchanged surface is reused without reading
guest memory, a CPU write is uploaded, and a driver store of the same
bytes is uploaded again because no snapshot is left to compare.
