Rollup merge of #130954 - workingjubilee:stabilize-const-mut-fn, r=RalfJung
Stabilize const `ptr::write*` and `mem::replace`
Since `const_mut_refs` and `const_refs_to_cell` have been stabilized, we may now also stabilize the ability to write to places during const evaluation inside our library API. So, we now propose the `const fn` version of `ptr::write` and its variants. This allows us to also stabilize `mem::replace` and `ptr::replace`.
- const `mem::replace`: https://github.com/rust-lang/rust/issues/83164#issuecomment-2338660862
- const `ptr::write{,_bytes,_unaligned}`: https://github.com/rust-lang/rust/issues/86302#issuecomment-2330275266
Their implementation requires an additional internal stabilization of `const_intrinsic_forget`, which is required for `*::write*` and thus `*::replace`. Thus we const-stabilize the internal intrinsics `forget`, `write_bytes`, and `write_via_move`.
