Evict alloc/free stack traces from the stack depot for Generic KASAN once
they are evicted from the quaratine.

For auxiliary stack traces, evict the oldest stack trace once a new one is
saved (KASAN only keeps references to the last two).

Also evict all saved stack traces on krealloc.

To avoid double-evicting and mis-evicting stack traces (in case KASAN's
metadata was corrupted), reset KASAN's per-object metadata that stores
stack depot handles when the object is initialized and when it's evicted
from the quarantine.

Note that stack_depot_put is no-op if the handle is 0.
