Merge bitcoin/bitcoin#33626: ci: run native fuzz with MSAN job

Browse Source 
1e6e32fa8a ci: run native fuzz with MSAN job (fanquake)
3784d15bcd ci: use LLVM libcxx 21.1.5 (fanquake)

Pull request description:

  I think this job should exist in this repo (not just qa-assets), if the alternative is double-handling changes to the interpreter. #32998 made changes which were then re-changed in #33600, to work around a false positive.

  The unchached runtime of this job with `-lg` is `~32m`, with `-md` it's `~43m`.

  Timeout is set to 150m, as the slow GHA runners were close to hitting a 120m limit.
