Do not cache `lints_that_dont_need_to_run` across sessions
The `lints_that_dont_need_to_run` query depends on the lint store (which includes internal lints under `-Zunstable-options`). Because that flag is deliberately not part of the incremental command-line hash, incremental builds could load stale results from sessions with a different lint configuration, leading to an ICE.
This PR marks the query `eval_always` so it is recomputed for the current session instead of being loaded from cache.
Fixesrust-lang/rust#156182.
