[AllocBoxToStack] Use `SILBUilderWithScope` instead of `SILBuilder`.
[AllocBoxToStack] Use `SILBUilderWithScope` instead of `SILBuilder`.

It's the correct thing to do, as we immediately switch the current
debug scope. In this case, it's NFC as the code was already doing
the right thing, but this is more concise/harder to get wrong.
