Making Arc::<[T]>::make_mut() valid. Maybe improving the entire story for DSTs.

* `{Rc,Arc}::make_mut()` now accept any type implementing the new unstable trait… `core::clone::CloneToUninit`. * `CloneToUninit` is implemented for `T: Clone` and for `[T] where T: Clone`. * `CloneToUninit` is a generalization of the existing internal trait `alloc::alloc::WriteCloneIntoRaw`. * New feature gate: `clone_to_uninit` This allows performing `make_mut()` on `Rc<[T]>` and `Arc<[T]>`, which was not previously possible. --- Previous PR description, now obsolete: > Add `{Rc, Arc}::make_mut_slice()` > > These functions behave identically to `make_mut()`, but operate on `Arc<[T]>` instead of `Arc<T>`. > > This allows performing the operation on slices, which was not previously possible because `make_mut()` requires `T: Clone` (and slices, being `!Sized`, do not and currently cannot implement `Clone`). > > Feature gate: `make_mut_slice`
