Add `keep-stage-std` to `x.py`
This keeps only the `std` artifacts compiled by the given stage, not the compiler. This is useful when working on the latter stages of the compiler in tandem with the standard library, since you don't have to rebuild the *entire* compiler when the standard library changes.
