Rollup merge of #111982 - jyn514:disable-incremental, r=Mark-Simulacrum
Revert "Enable incremental independent of stage"

This reverts commit 827f656ebb1230f31af6d968c4bfe69a79914ffc.

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 https://github.com/rust-lang/rust/pull/111329, this should fix https://github.com/rust-lang/rust/issues/76720.
