Rollup merge of #151396 - cache-cache, r=lqd

`rustc_queries!`: Don't push the `(cache)` modifier twice

Due to some kind of merge/rebase mishap in rust-lang/rust#101307 and rust-lang/rust#101173, we ended up with two copies of this query modifier.

Thankfully the redundant copy was harmless.

- rust-lang/rust#101307
