This reverts commit 827f656. Incremental is not sound to use across stages. Arbitrary changes to the compiler can invalidate the incremental cache - even changes to normal queries, not incremental itself! - and we do not currently enable `incremental-verify-ich` in bootstrap. Since 2018, we highly recommend and nudge users towards stage 1 builds instead of stage 2, and using `keep-stage` for anything other than libstd is very rare. I don't think the risk of unsoundness is worth the very minor speedup when building libstd. Disable incremental to avoid spurious panics and miscompilations when building with the stage 1 and 2 sysroot.

Combined with #111329, this should fix #76720.
