Auto merge of #109333 - Zoxc:erase-query-cache-values, r=cjgillot
Erase query cache values

This replaces most concrete query values `V` with `MaybeUninit<[u8; { size_of::<V>() }]>` without introducing dynamic dispatch like https://github.com/rust-lang/rust/pull/108638 does. This is split out of https://github.com/rust-lang/rust/pull/108638 so the performance impact of only this change can be measured.
