Auto merge of #116707 - cjgillot:slice-id, r=oli-obk,RalfJung
Create an `AllocId` for `ConstValue::Slice`. This PR modifies `ConstValue::Slice` to use an `AllocId` instead of directly manipulating the allocation. This was originally proposed by https://github.com/rust-lang/rust/pull/115764 but was a perf regression. Almost 2 years later, enough code has changed to make this a perf improvement: https://github.com/rust-lang/rust/pull/116707#issuecomment-3067158777
