Rollup merge of #58553 - scottmcm:more-ihle, r=Centril 
Use more impl header lifetime elision

Inspired by seeing explicit lifetimes on these two:

- https://doc.rust-lang.org/nightly/std/slice/struct.Iter.html#impl-FusedIterator
- https://doc.rust-lang.org/nightly/std/primitive.u32.html#impl-Not

And a follow-up to https://github.com/rust-lang/rust/pull/54687, that started using IHLE in libcore.

Most of the changes in here fall into two big categories:

- Removing lifetimes from common traits that can essentially never user a lifetime from an input (particularly `Drop`, `Debug`, and `Clone`)

- Forwarding impls that are only possible because the lifetime doesn't matter (like `impl<R: Read + ?Sized> Read for &mut R`)

I omitted things that seemed like they could be more controversial, like the handful of iterators that have a `Item: 'static` despite the iterator having a lifetime or the `PartialEq` implementations [where the flipped one cannot elide the lifetime](https://internals.rust-lang.org/t/impl-type-parameter-aliases/9403/2?u=scottmcm).

I also removed two lifetimes that turned out to be completely unused; see https://github.com/rust-lang/rust/issues/41960#issuecomment-464557423

libcore: Add VaList and variadic arg handling intrinsics

## Summary

 - Add intrinsics for `va_start`, `va_end`, `va_copy`, and `va_arg`.
 - Add `core::va_list::VaList` to `libcore`.

Part 1 of (at least) 3 for #44930

Comments and critiques are very much welcomed 😄

65204a97d4 Auto merge of #55278 - Centril:constification-1, r=alexcrichton 
Minor standard library constification

This PR makes some bits of the standard library into `const fn`s.
I've tried to be as aggressive as I possibly could in the constification.
The list is rather small due to how restrictive `const fn` is at the moment.
