[llvm] [LLVM] Update backend maintainer (PR #116622)

[Nikita Popov via llvm-commits]

https://github.com/nikic created https://github.com/llvm/llvm-project/pull/116622

We currently list Evan Cheng as the fallback maintainer for the LLVM backend. However, their last contribution dates back to 2014...

I'd like to nominate @arsenm instead, who is our most active backend reviewer.
