Rollup merge of #77120 - ecstatic-morse:keep-stage-std, r=Mark-Simulacrum
Add `--keep-stage-std` to `x.py` for keeping only standard library artifacts

Unlike `--keep-stage 0`, `--keep-stage-std 0` will allow the stage 0 compiler artifacts (i.e., stage1/bin/rustc) to be rebuilt if it has changed. This allows contributors to iterate on later stages of the compiler in tandem with the standard library without needing to to rebuild the entire compiler. I often run into this when working on const-checking, since I may need to add a feature gate or make a small tweak to the standard library.
