Introducing: Lime, a new series of CPUs.

Virtual CPUs, that is. Or rather, Virtual CPU feature sets 😃.

So far, LLVM only has one Wasm CPU defined which is stable, "mvp". The "generic" and "bleeding-edge" CPUs evolve (carefully) over time, which works well for many users, but not all. "lime1" is a new CPU tools like LLVM can target which is an update to "mvp", and which is intended to be stable.

A patch adding lime1 to LLVM is here: https://github.com/llvm/llvm-project/pull/112035
