Auto merge of #57770 - Zoxc:no-hash-query, r=michaelwoerister

Add a query type which is always marked as red if it runs

This is useful for queries which produce results which are very likely to change if their inputs do.

I also expect this to be useful for end to end queries because 1) we don't need `HashStable` impls and 2) we avoid the overhead of hashing the result of large results like the AST or the HIR map.
