`std::vec`: Add UB check for `set_len`, `from_raw_parts_in`, and etc. Closes rust-lang/rust#143813 I noticed that `from_parts_in` do the similar things like `from_raw_parts_in`, so I add the UB check in the last commit. If it is not appropriate, I will remove it. And I fix a typo in the first commit. r? `@scottmcm`

update issue number for `const_trait_impl`

Add `Vec::into_chunks` Tracking issue rust-lang/rust#142137

Also applies to `Vec::into_raw_parts`. The expectation is that you can round-trip these methods with `from_raw`, but this is only true when using the global allocator. With custom allocators you should instead be using `into_raw_with_allocator` and `from_raw_in`. The implementation of `Box::leak` is changed to use `Box::into_raw_with_allocator` and explicitly leak the allocator (which was already the existing behavior). This is because, for `leak` to be safe, the allocator must not free its underlying backing store. The `Allocator` trait only guarantees that allocated memory remains valid until the allocator is dropped.
