Filter out KASAN-related stack frames in reports like KCSAN does [1].

Comment 1 Andrey Konovalov 2024-12-03 22:06:34 UTC 
There's a proof-of-concept patch for this issue sent by Nihar Chaithanya [1]. The patch still needs work and testing as pointed by Marco in the thread. Also see my comments for the previous versions of the same patch (search lore.kernel.org).
