Rollup merge of rust-lang#108047 - oli-obk:machine->🞋, r=RalfJung

Use `target` instead of `machine` for mir interpreter integer handling.

The naming of `machine` only makes sense from a mir interpreter internals perspective, but outside users talk about the `target` platform. As per rust-lang#108029 (comment)
